We recommend Torque Pro. The camshaft position sensor CMP is used to determine the position of the camshaft s. It relays this information to the powertrain control module PCM. The PCM then uses this information to control the fuel injectors, and on some applications, for ignition timing. This information is used but the PCM to control ignition timing, and in some applications, it is also used to control fuel injection.

Should the timing be off, the PCM will set a code P To sum things up, the common causes for code P are as follows:. Due to the high number of possible causes of code P, as well as the wide range of current prices of replacement parts for every possible part that can fail and set this code as a result, it is not possible to provide a repair cost estimate for this code that is even reasonably accurate for any part of the USA.

However, this resource offers a cost estimator that lists both parts and labor costs for all popular makes and models in all areas of the US market.

Code P may be accompanied by several different symptoms. These including: an engine that runs poorly, an engine that cranks but will not start and an illuminated check engine light. Note that PCM failures are rare. Code P should be considered serious, since the vehicle can be completely immobilized if the correlation between the crankshaft and camshaft position sensors fails completely. Moreover, depending on the application and the nature of the problem, some types of engines interference type engines with timing belts can suffer serious, if not always fatal damage should the timing belt break or slip.

Ideally, a vehicle with this code should not be driven until the fault is found and repaired, and especially not in traffic, since the engine can stall at any time.You may be entitled to a refund, replacement or cash compensation.

P0016 โ€“ Meaning, Causes, Symptoms, & Fixes

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?

Why is the Engine Light ON? Repair Importance Level: 3.The correlation of the camshaft and crankshaft positions on bank 1 is incorrect based on the intake camshaft position sensor. In order for the engine to run smoothly and efficiently, it has to know exactly where the camshaft and crankshaft is in its rotation.

If the Engine Control Module ECM detects that the bank 1 intake camshaft and crankshaft are not in the correct position, it will trigger code P This trouble code can cause the vehicle to be hard to start and run rough. In some cases, the vehicle may not be driveable. It should be addressed as soon as possible. For error code P, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair.

Hello I have a jeep Compas a check for a code and it says my camshaft position sensor need to be replace I replaced it and the check engine light is still on what do you think it could be. Not to sure but I have a Clk is a very similar engine is located on the front of the engine on the right hand side as you seated on the car as 2 sensors exactly the same.

Have you solved the P problem? What was the cause and solution? I have the P code; is the same only for sensor B. I have a trusted mechanic that recommended leaving this alone on my Avalanche.

He said it might fix the issue but he had no way of knowing now if there was internal engine damage due to the problem. He said it could run for a week and clunk out or go for a long time. I chose to run it til it blows up.

A year later, still runs fine. Yes No Hi, I have recently had a bit of work done on my car, the original faults were the timing chain, crankshaft sensor, thermostat and coolant sensor all needed replacing which has been done and the timing which was originally miles out is now in and the engine sounds nice and runs okay, whilst doing this the mechanic also found the third coil was completely gone so it then had a new coil pack and spark plugs.

The codes P and P were not there before the work was done, however the engine management light has now come on and the diagnostics are showing these codes. Any ideas? The timing is fine, the sensors have been tested and are all working, the ecu has been wiped which briefly removed the eml however after two minutes it was straight back on? Do you. Hi Matt, The P code means that the camshaft position sensor for bank 1 is correlating with the signal from the crankshaft position sensor, in other words there is a discrepancy between the timing of the crankshaft and the intake camshaft sensor this discrepancy exceeds 10 degrees at idle.

Possible causes; the timing chain has jumped teeth, problems with the phaser the camshaft phaser is out of position, the timing chain has jumped teeth, it could be caused by the oil flow to the phase has been impeded partially clogged passages, there could be some restriction in oil control valve filter or possibly the wrong oil viscosity.

Regarding the P code; There is a discrepancy between the crankshaft and camshaft positioner bank 1 they are not in-sync with each other. I would try replacing the oil control solenoid because they can plug not supplying oil pressure to the camshaft actuator.

Malls struggle to replace these anchor stores, which typically take up prime real estate. Stores like Gap and Nordstrom will thrive by becoming destinations that offer more than just clothing. Flashy gimmicks and personalized service will turn shopping from a casual pastime into an anticipated event. Bezos missed the mark on this one, but he's not far off. Although retail is suffering big time, it's not for lack of trying. As retailers struggle to attract customers, they admit that making the in-store experience more exciting is crucial, but few have cracked how to do so successfully, CNBC reports.

But as retail sales continue to slip, it seems they'll have to keep pushing for a more complete breakthrough. And according to Business Insider, movie theaters aren't doing so well either.
