DTC P0335:00

CKP sensor circuit problem

DETECTION CONDITION

•  If the PCM does not receive the input voltage from the CKP sensor for 4.2 s or more while the MAF is 1.43 g/s {0.189 lb/min} or more, the PCM determines that there is a CKP sensor circuit problem.

2		No	Go to the next step.
3	INSPECT CKP SENSOR CONNECTOR CONDITION • Switch the ignition off. • Disconnect the CKP sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 10.
3		No	Go to the next step.
4	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 10.
4		No	Go to the next step.
5	INSPECT CKP SENSOR CIRCUIT FOR SHORT TO GROUND • Verify that the CKP sensor and PCM connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side) and body ground: ― CKP sensor terminal A ― CKP sensor terminal B • Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • CKP sensor terminal A—PCM terminal 2O • CKP sensor terminal B—PCM terminal 2AH If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to ground. Go to Step 10.
5		No	Go to the next step.
6	INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • Verify that the CKP sensor and PCM connectors are disconnected. • Switch the ignition ON (engine off). Note • Another DTC may be stored by the PCM detecting an open circuit. • Measure the voltage at the CKP sensor terminal B (wiring harness-side). • Is the voltage 0 V?	Yes	Go to the next step.
6		No	Refer to the wiring diagram and verify whether or not there is a common connector between CKP sensor terminal B and PCM terminal 2AH. If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to power supply. Go to Step 10.
7	INSPECT CKP SENSOR CIRCUITS FOR SHORT TO EACH OTHER • Verify that the CKP sensor and PCM connectors are disconnected. • Switch the ignition off. • Inspect for continuity between CKP sensor terminals A, B and C (wiring harness-side). • Is there continuity?
