P0335 P0336 | Crankshaft Position Sensor Circuit Malfunction Crankshaft Position Sensor Circuit Out of Range |
DESCRIPTION
The Crankshaft Position (CKP) sensor consists of a magnet and coil locatednext to the flywheel. The sensing wheel teeth are used by the CKP sensor togenerate a signal. The voltage signal from CKP sensor allows the Engine ControlModule (ECM)to determine engine RPM and crankshaft position.
FAILURE CONDITIONS
[FOR P0335]
The ECM will set P0335 and the MIL will turn on if the CKP signal voltageremains at 0.0 volts with the starter engaged for 4 seconds or 8 revolutionsand the Camshaft Position (CMP) sensor signal indicating engine rotation Thischeck is made every time the engine starts. This code indicates no crankshaftsignal is being read by the CKP sensor or the ECM while aCMP sensor signalverifies engine rotation.
[FOR P0336]
The ECM will set P0336 and the MIL will turn on immediately if the CKPsensor signal does not indicate the two missing teeth in exactly the sameposition on the tone wheel during two successive engine revolutions. Thischeck is made for 5 seconds when the engine is running above 2000 RPM. Thiscode indicates a problem with the crankshaft being read by the CKP sensoror ECM.
