How do I fix code P1345?
Loose the distributor hold down bolt with engine OFF. Make sure your OBD scanner is plugged in to monitor the Cam Retard Offset reading. Turn the engine on, let it warm to normal operating temps, and get the rpm’s above 1,000. If your reading is negative, turn the distributor counterclockwise.
What causes a P1345 code?
In many cases, this code is usually caused by simple electrical connection failure or a failed camshaft sensor. Loose CKS and CMS are also possible, but highly unlikely. If there has been a misfire or failed sensor, then an additional code will come with P1345.
Is it bad to drive with a bad crankshaft sensor?
”It is not safe to drive with a bad crankshaft position sensor because if the crankshaft position sensor is faulty, it can no longer supply the engine control unit with correct information about the position of the crankshaft.
What happens if a crankshaft sensor goes bad?
If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. This is usually a symptom of a wiring problem, however a bad crankshaft position sensor can also produce this symptom.
How do I know my crankshaft is bad?
Symptoms of a Bad or Failing Crankshaft Position Sensor
- Issues Starting the Vehicle.
- Intermittent Stalling.
- Check Engine Light Comes On.
- Uneven Acceleration.
- Engine Misfires or Vibrates.
- Rough Idle and/or Vibrating Engine.
- Reduced Gas Mileage.
Does crank sensor control injectors?
The crank position sensor also manages fuel injector function in vehicles with distributorless ignition systems. A failed crank position sensor may not trigger fuel injectors at all which will result in a no-start condition for the vehicle.
Can I drive with a bad crankshaft position sensor?
What do you need to know about p1345 GMC?
P1345 Gmc Description. The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. 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.
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 -, and Camshaft Position sensors that exceeds a maximum
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-
