Code P0335 Chevrolet Description

The crankshaft position sensor is an internally magnetic biased digital output integrated circuit sensing device. The sensor detects magnetic flux changes in the teeth and slots of the reluctor wheel on the crankshaft. The reluctor wheel is spaced at 60-tooth spacing, with two missing teeth for the reference gap. The reference gap is used to identify the crankshaft position at each start-up. The crankshaft position sensor produces an ON/OFF DC voltage of varying frequency, with 58 output pulses per crankshaft revolution. The crankshaft position sensor sends a digital signal to the ECM as each tooth on the reluctor wheel rotates past the crankshaft position sensor. The ECM uses each crankshaft position signal pulse to determine the crankshaft speed position. This information is then used to determine the optimum ignition and injection points of the engine. The ECM also uses crankshaft position sensor output information to determine the camshaft's relative position to the crankshaft, control camshaft phasing, and detect cylinder misfire.
The ECM also has a dedicated replicated crankshaft position sensor signal output circuit that may be used as an input signal to other modules for monitoring engine RPM.
The Diagnostic Trouble Code (DTC) will be set when no signal is sent from the Crankshaft Position Sensor to the ECM for greater than 1s.

Code Tech Notes

User Submitted Video

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.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P0335 Chevrolet code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
