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.

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.

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. So, what happens when that engine timing is thrown out of whack? Intake and exhaust valves , all randomly working without any rhythm. At the very least, your car will suffer some serious performance penalties. So, what does that P diagnostics trouble code mean, then? Respectively, they monitor, analyze, and oversee the speed and positioning of both the crankshaft as well as the camshaft, accordingly.

Thank you for your time etc. GreenandChrome Replies. Depending on the part that has failed, driving the vehicle for any lengthy period may cause additional internal engine problems. Category: Car advice 18th October The timing chain may have issues with guides or tensioners, leading to engine damage if the valves hit the pistons. Copy link. 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. Just sometimes it wont kick over and start. Sort by Oldest first Oldest first Newest first Most reactions. 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. Ask Cancel.

A change of oil and filter should be done if the oil is filthy.

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.

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. The timing chain may have issues with guides or tensioners, leading to engine damage if the valves hit the pistons. For a better experience, please enable JavaScript in your browser before proceeding. If the camshaft position sensor fails to do its job, the engine will have a rough idle, low fuel efficiency, and subpar performance. I have 2 issues happening. I drive it a very short distance, maybe a mile, turn off the car, run in and grab lunch, and then when I get back into my car and try to start it, it cranks 4 or 5 extra cranks before finally starting. All I did was replace the camshaft position sensor part number 07L C and it cleared it right up. In the same way that the timing chain seldom breaks, the timing belt rarely does either. I don't know if they're related, so here's a complete rundown: On a cold start in the morning, car will start and run fine. Camshaft position sensors track the rotational rate and location of the cams. Fixter is revolutionising the car maintenance industry, one repair at a time.
