DTC P0335 - LNP or LNQ

The crankshaft position sensor is located on the left rear of the engine block. The crankshaft position sensor produces an AC voltage of different amplitude and frequency depending on the velocity of the crankshaft. The crankshaft position sensor works in conjunction with a 58 X reluctor wheel that is attached to the crankshaft. Each tooth on the reluctor wheel are spaced 6 ° apart with one span having a 12 ° space. The engine control module (ECM) uses the 12 ° space to determine top dead centre for cylinder 1 and cylinder 4. The ECM determines when cylinder 1 is on the compression stroke by monitoring the crankshaft position sensor and the camshaft position sensors. The ECM can synchronise the ignition timing and fuel injector timing based on the crankshaft position sensor and the camshaft position sensor inputs.

P0335 00

The ECM does not detect a signal from the crankshaft position sensor. Or, the ECM detects a crankshaft position signal without reference pulse.

1. Clear the DTC Info with a scan tool. Attempt to start the engine, observe the DTC information with a scan tool. DTC P0335 should not set.
2. Move related harnesses/connectors of the B26 Crankshaft Position Sensor and verify the engine does not stumble, stall, or change engine speed.
3. 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.

1. Ignition OFF, disconnect the harness connector at the B26 Crankshaft Position Sensor.
2. Ignition ON, test for 2-3 V between the high signal circuit terminal 1 and ground.

⇒	If less than the specified range, test the high signal circuit for an open/high resistance or for a short to ground. If the circuit tests normal, replace the K20 Engine Control Module.

⇒	If greater than the specified range, test the high signal circuit for a short to voltage. If the circuit tests normal, replace the K20 Engine Control Module.

3. Ignition ON, test for 2-3 V between the low signal circuit terminal 2 and ground.

⇒	If less than the specified range, test the low signal circuit for an open/high resistance or for a short to ground. If the circuit tests normal, replace the K20 Engine Control Module.

⇒	If greater than the specified range, test the low signal circuit for a short to voltage. If the circuit tests normal, replace the K20 Engine Control Module.

4. If all circuits test normal, test or replace the B26 Crankshaft Position Sensor.

Dynamic Test

1. Ignition OFF, disconnect the harness connector at the B26 Crankshaft Position Sensor.

Note: If the Crankshaft Position Sensor lead is damaged in any way, replace the B26 Crankshaft Position Sensor.

2. Test for 700-1 200 Ω between the high signal terminal 1 and the low signal terminal 2.

⇒	If not within the specified range, replace the B26 Crankshaft Position Sensor.

3. Set the DMM to the AC voltage scale.
4. Engine cranking, test for greater than 1.3 V AC between the high signal terminal 1 and the low signal terminal 2.

⇒	If less than the specified range, replace the B26 Crankshaft Position Sensor.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
