Crankshaft Position Sensor ‘A’ Circuit Malfunction
Table of contents
P0335 PONTIAC Possible Causes
- Faulty crankshaft position sensor
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
How do I fix code P0335 PONTIAC?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P0335 PONTIAC code
The cost of diagnosing the P0335 PONTIAC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
The Powertrain Control Module (PCM) determines no signal from the Crankshaft Position (CKP) sensor for less than 3 seconds.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible lack/loss of Power
- Engine may stall while driving
P0335 PONTIAC Description
The Crankshaft Position Sensor (CKP) works in conjunction with a 24X reluctor wheel mounted on the rear of the crankshaft. The CKP sensor has a B+ power supply, a ground, and a signal circuit. As the crankshaft rotates, the reluctor wheel teeth interrupt a magnetic field produced by a magnet within the sensor. The sensor’s internal circuitry detects this and produces a signal which the Powertrain Control Module (PCM) reads. The PCM uses this signal to accurately measure crankshaft velocity which is a variable used in order to detect misfire, spark and, fueling.
