P is the OBD-II generic code indicating that the crankshaft and camshaft position sensor for bank 1 exhaust camshaft do not correlate signals with each other. There are oil flow problems to the phaser from incorrect oil viscosity or partly clogged passages. Note : The drive complaints may vary depending on the manufacturer failure mode during a problem with the system.

Does a visual check for problems with the connections or wiring of the OCV, camshaft and crankshaft sensors. Scans and documents the engine codes, then views the freeze frame data to see when the codes were set. Commands the OCV on and off to see if the camshaft sensor is indicating timing changes for the bank 1 exhaust camshaft.

Note: The manufacturer's recommended pinpoint test is used to narrow down the problem. Following the recommended tests will help with diagnosis without replacing the wrong parts. Repairing or replacing components that are were not directed by the pinpoint test or visual check. Timing chains may have tensioners or guides that are allowing the timing chain to jump the gear teeth, leading to major engine damage from valves and pistons hitting.

Driving the vehicle for a prolonged time with the camshaft problems can start to cause other drive symptoms like misfires, stalling, and no starts. Code P can cause the engine to get carbon build up inside the cylinder and on the valves. This is caused from improper combustion of the fuel mixture from camshaft alignment problems. The engine may need to be decarbonized after repairs are made.

What are the symptoms of the P code? The engine may idle normally, but have a reduction in power. The engine may run erratically or run rough on acceleration.Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, 6 of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees after one of the 60 degree slots.

The CKP sensor produces seven pulses for each revolution of the crankshaft. The pulse from the 10 degree slot is known as the sync pulse. The sync pulse is used to synchronize the coil firing sequence with the crankshaft position. The Camshaft Position CMP sensor is triggered by a notched reluctor wheel built into the exhaust camshaft sprocket. The CMP sensor provides 6 signal pulses every camshaft revolution. Each notch, or feature of the reluctor wheel is of a different size for individual cylinder identification.

This relationship is used to determine camshaft actuator position and control its phasing at the correct value. The PCM also uses this signal to identify the compression stroke of each cylinder, and for sequential fuel injection. Get Access to Factory Service Manuals. Need more help?

What are the symptoms on your vehicle for the P Chevrolet code? Have you replaced any parts? Any information is appreciated. Repair Importance Level: 3.Engine Performance problem Chevy Colorado Automatic 40, miles I am having a problem with my truck running rough. I have a check engine code p I know I'm having trouble with the timing between the crank sensor and the cam actuator. What do I do? Do you. Can be anything from a bad actuator, test it by removing the actuator and applying 12v, does the pintle move?

If yes it's OK, next is the harmonic balancer and the bolt check for proper torque, and watch the balancer, does it look normal? Can also be the timing chain and or the gears. Also consider this Tech Bulliten from GM. Some circuits in vehicles are not only susceptible to an intermittent connection, but high resistance may also cause erratic operation or DTCs. An often overlooked possibility in the diagnostics of intermittents is the quality of the terminal crimps. Inspect and ensure the integrity of all related wiring harness connectors.

If the wiring harness connectors are not properly constructed or engaged before they are locked together, numerous types of intermittent conditions can occur, which may include any of the symptoms listed in the Subject title above and possibly others.

Supercedes: This bulletin is being revised to add additional information and to provide a dedicated Labor Operation for Recrimping Electrical Terminals. NOTE: In some circuits where modules compare electrical values to determine proper operation or function, resistance differences as small as "milli-ohms" may cause Diagnostic Trouble Codes DTCs to set.

P0017 CHRYSLER - Crankshaft-Camshaft Timing Misalignment Bank 1 Sensor 2

Please login or register to post a reply. Sponsored links. Ask a Car Question. It's Free!P in the Chevy Colorado is predominantly caused by a few different things. It is typically thrown when the Crankshaft Position Sensor and the Camshaft Position Sensor are out of alignment by a certain number of degrees, or if there is an issue with the wiring, or one of the sensors themselves may have gone bad.

P refers to which camshaft position sensor is out of time with the Crankshaft. P should be considered an important trouble code to diagnose and repair. When this timing is off, the engine will typically not run or barely run. Here are the most common causes of P in the Colorado, as well as diagnostic advice, and resources to further explore.

One of the most common causes of P in any vehicle is going to be wiring issues. This is a great place to start diagnosing P in your Colorado. After examining the wiring harness, it would be time to check the sensors themselves.

We linked to a great video showing you how to do so directly below. How to test a crankshaft or camshaft sensor YouTube. Camshaft Position Sensor Amazon. The timing chain or belt will throw cause P to throw.

This will happen when it has stretched or jumped a tooth or two. If it jumps more than a few teeth, the odds are that the engine itself will not run at all. Many manufacturers particularly Japanese Automakers have very strict timing chain service intervals. Even the slightest misalignment can cause P Timing Chain Jumped Symptoms and Diagnosis. The Crankshaft Sensor is going to use a tone or reluctor ring to determine the position of the Crank. This ring uses notches that are scanned by the Crank Sensor in order to get an accurate position.

If this ring fails, the Colorado will not be able to get an exact crank position. The camshaft typically will have a ring that provides the same function. That is a very good indication that there is an issue with it.

Good luck diagnosing P in the Chevy Colorado. If there is anything you would like to add, please leave a comment below. Wiring Issues One of the most common causes of P in any vehicle is going to be wiring issues. Make sure to check the harness where it plugs into both sensors as well.Post a Comment. If the PCM detect a defference that exceeds a calibrated threshold, a fault is detected.

Is the DTC active or pending P code? YES, go to step 2. NO, perform the PCM intermittent condition. Step 2. Failure to do so may lead to misdiagnosis :.We recommend Torque Pro. The complex ballet of mechanical and electrical parts in your engine make it possible to harness the power locked away in every drop of fuel injected into the cylinders.

As is the case with many things in life, timing is absolutely critical. Mechanically-speaking, the timing in relationship to the crankshaft and camshafts must be precise, which is the function of the timing sprockets and timing belt or timing chains.

Depending on the engine, the crankshaft may be connected to the camshaft s by a belt or chain and dual-overhead camshafts may be connected by gears or chains. Timing precision is absolutely necessary, not only for good engine performance, fuel economy, and emissions-reduction, but also to prevent damage to the engine itself. As the crankshaft pushes cylinder 1 up to top-dead-center TDC on the compression stroke, the valves for cylinder 1 should be closing, and the spark plug should be firing, for example.

If timing is off by a few degrees, the results could range from poor performance and fuel economy to catastrophic engine failure. Regarding timing, to keep the engine running properly, the engine control module ECM continually monitors the crankshaft position sensor CKP and camshaft position sensors CMP.

The main cause of DTC P is stretched timing chains. Aside from the MIL, you may or may not notice any drivability problems. Symptoms may range from poor fuel economy to rough idle and poor engine performance. You may notice excessive noise from the front of the engine, under the timing covers.

It does one good to note that this typically not a sensor problem, since the ECM can only use good sensor readings to determine whether or not the engine is in time. That having been said, diagnosing timing problems may best be left to the professionals, particularly if your vehicle is still covered under warranty. Always double check warranty application before opening up something as critical as the timing covers. With an up-to-date repair manual, experienced DIYers may be able to diagnose this problem, though the availability of special tools may limit repair ability.

Notify of. Thomasine Williams. Diane Ovitt. Next Post Next P — Fuel pressure regulator -performance problem.Meaning of P engine trouble code is a kind of powertrain trouble code and P if your catalytic convertor fails completely, you eventually won't be able to keep the car running. Your gas mileage will also be terrible, so you should try and fix it as soon as you can. Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder.

In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank.

As a result, the engine stutters or backfires, if it runs at all. The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate.

P DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
