Diagnostic Fault Information

Circuit	Short to Ground	Open/High Resistance	Short to Voltage	Signal Performance
CKP Sensor 5-Volt Reference Circuit	P0335, P0651	P0335	P0335, P0651	P0336

Low Reference	--	P0335	--	P0336

The crankshaft position (CKP) sensor signal detects crankshaft speed and position. The CKP sensor produces an AC voltage of different amplitude and frequency. The frequency depends on the velocity of the crankshaft, and the AC voltage output depends on the crankshaft position and battery voltage. The CKP sensor works in conjunction with a 58X reluctor wheel attached to the crankshaft. The engine control module (ECM) can synchronize the ignition timing, fuel injector timing, and spark knock control based on the CKP and the camshaft position (CMP) sensor inputs. The CKP sensor is also used to detect misfire and tachometer display.

Conditions for Running the DTC

•	DTCs P0101, P0102, P0103, P0365, P0366, P0641, and P0651 are not set.

•	The engine is cranking or running.

•	The airflow into the engine is greater than 3 g/s.

•	The DTCs run continuously once the above conditions are met.

Conditions for Setting the DTC

DTC P0335 sets if one of the following conditions occur:

•	The ECM detects that the engine has been cranking for greater than 15 seconds without a CKP sensor pulse.

•	The engine is operating and the ECM does not detect a CKP pulse for 10 seconds.

DTC P0336 sets if one of the following conditions occur:

•	The ECM detects that the engine has been cranking for greater than 1.5 seconds without detecting the synchronization gap on the reluctor wheel.

•	The ECM detects that the engine is running, but greater than 25 crankshaft resyncs have occurred within 20 seconds.

•	The ECM detects that the engine is running without detecting the synchronization gap on the reluctor wheel.

•	The ECM detects that the engine is running, but receives less than 51 or greater than 65 CKP sensor pulses, during one engine revolution.

Action Taken When the DTC Sets

•	DTCs P0335 and P0336 are Type B DTCs.

•	The ECM will use the camshaft position (CMP) sensor for engine operation.

Conditions for Clearing the DTC

DTCs P0335 and P0336 are Type B DTCs.

Diagnostic Aids

•	The following conditions could also set the DTCs:

-	Physical damage to the CKP sensor or the reluctor wheel

-	Excessive play or looseness of the CKP sensor or the reluctor wheel

-	Improper installation of the CKP sensor or the reluctor wheel

-	Foreign material passing between the CKP sensor and the reluctor wheel

-	Excessive air gap between the CKP sensor and the reluctor wheel

•	If there is a condition with the CKP sensor, the tachometer will be inoperative.

•	The CKP sensor may be out of range after a hot soak. Review the freeze frame or failure records for engine coolant temperature when the DTC set.

•	The ECM uses the camshaft position sensors to determine engine speed and position when there is a CKP sensor condition.

Circuit/System Verification

Note: If you were sent here from Engine Cranks but Does Not Run proceed to Circuit/System Testing.

Ignition ON, observe the DTC information with a scan tool. Verify DTC P0341, P0366, or P0651 are not set.

⇒	If DTC P0341 or P0366 is set, refer to DTC P0341 or P0366 for further diagnosis.

⇒	If DTC P0651 is set, refer to DTC P0641, P0651, P0697, or P06A3 for further diagnosis.

Attempt to start the engine, observe the DTC information with a scan tool. DTC P0335 and P0336 should not set.
Engine cranking, observe the scan tool Engine Speed parameter. The scan tool should indicate an engine speed greater than 0 RPM.
Move related harnesses/connectors of the CKP sensor and verify the engine does not stumble, stall, or change engine speed.

⇒	If the above condition exists, repair the harness/connectors as necessary.

Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

Note: If the CKP sensor lead is damaged in any way, replace the CKP sensor.

Ignition OFF, disconnect the harness connector at the CKP sensor.
Ignition OFF for 1 minute, test for less than 5 Ω between the low reference circuit terminal 2 and ground.

⇒	If greater than the specified range, test the circuit for an open/high resistance. If the circuit tests normal, replace the ECM.

Ignition ON, test for 4.8-5.2 V between the 5-volt reference circuit terminal 3 and ground.

⇒	If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.

⇒	If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM.

Test for 4.8-5.2 V between the signal circuit terminal 1 and ground.

⇒	If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.

⇒	If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the ECM.

Ignition OFF, connect a 3 A fused jumper wire to the CKP signal circuit terminal 1.
Ignition ON, momentarily touch the end of the fused jumper wire to ground while monitoring the scan tool CKP active counter. The CKP active counter should increment.

⇒	If the CKP active counter does not increment, replace the ECM.

If all circuits test normal, replace the CKP sensor.
