P0336 CHEVROLET Possible Causes
- Faulty crankshaft position sensor
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead or weak battery
How do I fix code P0336 CHEVROLET?
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.
Tech Notes
- On some 2011-2015 Volt and 2014 ELR models, DTC P0335 (Crankshaft Position Sensor Circuit) and/or P0336 (Crankshaft Position Sensor Performance) may be stored in history in the T6 Power Inverter Module (Hybrid Powertrain Control Module, or HPCM).
- If DTCs P0335 and/or P0336 are stored in history, check that ground locations G106 (engine block) (Below Figure – A) and G113 (drive unit case) (Below Figure – B) are clean and tight. On rare occasions, the bolt hole for G113 may not be drilled to the proper depth, which will cause the ground bolt to bottom out in the hole and result in low clamp load on the ground eyelet.
Cost of diagnosing the P0336 CHEVROLET code
The cost of diagnosing the P0336 CHEVROLET 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 crankshaft position sensor (POS) signal is not detected by the Powertrain Control Module (PCM) during the first few seconds of engine cranking
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine Cranks but Does Not Start
- Lack/Loss of Power
- Engine Stall
P0336 CHEVROLET Description
The Crankshaft Position Sensor (CKP) also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Powertrain Control Module (PCM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
