Because of this, a proper diagnosis may prove to be quite challenging. The Powertrain Control Module PCM has detected a misalignment of the crank or camshaft and has set the appropriate error code. When the shaft timing is wrong, the engine will have a very tough time running. No driving on it is recommended unless you intend to take it in for service. The engine will be exceedingly difficult to start, if not impossible to start at all, and it will run extremely roughly as a result. Extensive engine damage may occur if a stretched timing chain or worn timing belt is overlooked for too long.

Back to fixter. The PCM uses that data to control the fuel injectors for ignition timing to keep cylinders firing efficiently. On most vehicle applications, the camshaft position sensor is located near the cylinder head so that the CMP is opposite the timing rotor attached to the engine camshaft. The timing chain may have issues with guides or tensioners, leading to engine damage if the valves hit the pistons. Depending on the part that has failed, driving the vehicle for any lengthy period may cause additional internal engine problems. The car is likely to be hard to start, and once running, the engine may be hesitant and stall. The following are the most common symptoms:. In many cases, components such as the sensors are quickly replaced when far more common problems are behind a P OBD-II code. By carrying out a pinpoint test, helps avoid misdiagnosis and replacing good components. In some instances, resetting the fault code and performing a road test can solve the issue. However, if the cause is more severe than this, the following work may be necessary. If not, move on to the next repair:. Following that:.

There are a couple of things that can trigger this particular code. The camshaft and crankshaft must be in perfect correlation for the engine to work as it should. When this code is triggered, the car should be stopped right away and not driven before you diagnose and fix the issue. Replacing the timing chain is a part of regular car maintenance. Timing tensioners, chain guides and other components can fail causing the timing chain to stretch. Additionally, since timing chains are replaced at longer intervals, some drivers simply forget to service this critical part altogether. Jumped timing is also a pretty common cause for the P code, and it happens for the same reasons that cause timing chain stretching.

Imagine this… The intake valves open to allow air and fuel to enter the combustion chamber to be burnt. All the while, exhaust valves then open to enable fumes and by-products from that explosive cycle to escape out of the engine. At least, until P shows up.

BRealistic Replies. In the same way that the timing chain seldom breaks, the timing belt rarely does either. The rebuilt engine has RR4 printed on the side of the upper timing cover, but the trunk sticker shows it was an EA, so not sure which applies, or if it even matters. Do you have any suggestions to properly maintain it going forward? A little of effort is required to access it, much as the camshaft position sensor. Log in. No check engine light, No EPC light. Additionally, the factory-fresh roller or tensioner has a propensity to prematurely wear down. Feeling at a loss. Potential issues, causes, and solutions have been identified in the above article based on the experiences of car owners and repairers, as well as web materials such as forum blogs and technical support bulletins. In conclusion, please inform us in the comments if you are seeking for replacement parts or manuals for a different engine, and we would be happy to help you in any way that we can. Following that:. AVS Forum. Nor do I want another bricked engine while I'm waiting for the R to become available. Because of this, a proper diagnosis may prove to be quite challenging.

P is know to occur in the Volkswagen Golf when the Crankshaft Position Sensor and the Camshaft Position Sensor are out of alignment by a certain number of degrees, or if there is a sensor issue. 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.

Ask Cancel. I'd recommend changing that sooner than later. If your OBD-II scanner displays this code, we strongly suggest fixing it right away since, if the timing chain or belt is strained, this is a serious code. Sort by Oldest first Oldest first Newest first Most reactions. Somedays it runs perfect with no starting issues and other days I'll go grab a coffee and it will take x of cranking to kick my engine to start. You may drive on it a little bit longer than in the case described above if it turns out to be a cam or crank position sensor, but the timings of the engine will be wrong. I can easily repeat this exact scenario, and aside from the extra cranking required to start after a very short drive, the car has no other performance or starting issues. A timing chain drives the camshafts of an internal combustion engine, both the intake and the exhaust. That sensor sits right on top of the block, held on by a single T screw. Defective or corroded wiring or connections CKP sensor issue CMP sensor issue Stretched timing chain Mechanical faults such as the timing chain jumped teeth, a slipped reluctor ring on the crankshaft or slipped reluctor ring on bank 1 exhaust camshaft Camshaft phaser problem The oil flow to the phaser is hampered by an incorrect oil viscosity or partly clogged passages Oil Control Valve OCV has a restriction in the OCV filter.
