What causes p1345 on a camshaft position sensor?
What causes p1345 on a camshaft position sensor?
On these applications, excessive wear of the drive gears, or incorrect installation of the distributor are both roughly analogous to defective camshaft position sensors on applications that use distributor-less ignition systems. Nonetheless, some common causes of code P1345 could include the following-
When to use fault code p1345 in OBD II?
OBD II fault code P1345 is a code used by General Motors – that is defined as “Crankshaft Position (CKP)-Camshaft Position (CMP) Correlation”, and is set when the PCM (Powertrain Control Module) on GM models detects a mismatch (correlation fault) in the input data from the Crankshaft -,…
How does the camshaft and crankshaft position sensor work?
The camshaft and crankshaft position sensors monitor the location and speed of the camshaft and crankshaft. The camshaft position sensor monitors the rotation speed of the camshaft, which indicates valve position in the combustion cycle, while the crank position sensor monitors speed of crankshaft rotation, which gives piston location.
What does p1345 stand for in GM code?
NOTE: Note that code P1345 with the definition “Crankshaft Position (CKP)-Camshaft Position (CMP) Correlation”, is also used by closely related GM products, including Buick, Cadillac, Chevrolet, Isuzu, Pontiac, and Saturn.
On these applications, excessive wear of the drive gears, or incorrect installation of the distributor are both roughly analogous to defective camshaft position sensors on applications that use distributor-less ignition systems. Nonetheless, some common causes of code P1345 could include the following-
What should I do if I have a p1345 GMC code?
If a P0016 or P1345 is resetting without any engine performance concerns but the above information did not isolate a cause for the DTC, replace the Cam Phaser Actuator sprocket. The cost to diagnose the P1345 GMC code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city.
How does camshaft position affect fuel injection timing?
However, the engine also needs fuel delivered to the cylinders at the right time to run; so on most applications, the PCM uses input data from a camshaft position sensor to regulate the fuel injection timing. Note however that camshaft position sensors generally do not use reluctor rings to create a signal.
How does the camshaft position ( CMP ) sensor work?
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.
What causes a p1345 Chevy to go off the road?
P1345 CHEVROLET Possible Causes 1 Engine mechanical condition-Valve timing off 2 Cam sensor or crank sensor are loose on their mounting 3 Faulty camshaft position sensor 4 Faulty crankshaft position sensor
