DTC P0335:00

CKP sensor circuit malfunction

DETECTION CONDITION

•  If the PCM does not receive the input voltage from the CKP sensor for 4.2 s while the MAF is 2.0 g/s {0.26 lb/min.} or above, the PCM determines that the CKP sensor circuit has a malfunction.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  CKP sensor connector or terminals malfunction

•  Short to ground or open circuit in CKP sensor power supply circuit

―  Short to ground in wiring harness between main relay terminal C and CKP sensor terminal C

―  ENG BAR 15 A fuse malfunction

•  Short to ground in wiring harness between CKP sensor terminal B and PCM terminal 2W

•  PCM connector or terminals malfunction

•  Short to power supply in wiring harness between CKP sensor terminal B and PCM terminal 2W

•  CKP sensor signal circuit and ground circuit are shorted to each other.

•  Open circuit in wiring harness between the following terminals:

―  CKP sensor terminal B—PCM terminal 2W

―  CKP sensor terminal A—PCM terminal 2P

•  CKP sensor malfunction

―  CKP sensor pulse wheel malfunction

―  CKP sensor is dirty

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT CKP SENSOR CONNECTOR CONDITION • Switch the ignition to off. • Disconnect the CKP sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 11.
3		No	Go to the next step.
4	INSPECT CKP SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT • CKP sensor connector is disconnected. • Switch the ignition to ON (engine off). • Measure the voltage at the CKP sensor terminal C (wiring harness-side). • Is the voltage B+?	Yes	Go to the next step.
4		No	Inspect the ENG BAR 15 A fuse. • If the fuse is melt: ― Repair or replace the wiring harness for a possible short to ground. ― Replace the fuse. • If the fuse is deterioration: ― Replace the fuse. • If the fuse is normal: ― Repair or replace the wiring harness for a possible open circuit. Go to Step 11.
5	INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • CKP sensor connector is disconnected. • Switch the ignition to off. • Inspect for continuity between CKP sensor terminal B (wiring harness-side) and body ground. • Is there continuity?	Yes	If the short to ground circuit could be detected: • Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: • Replace the PCM (short to ground in PCM internal circuit). (See PCM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].) Go to Step 11.
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 11.
6		No	Go to the next step.
7	INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • CKP sensor and PCM connectors are disconnected. • Switch the ignition to ON (engine off). • Measure the voltage at the CKP sensor terminal B (wiring harness-side). • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 11.
7		No	Go to the next step.
8	INSPECT CKP SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER • CKP sensor and PCM connectors are disconnected. • Switch the ignition to off. • Inspect for continuity between CKP sensor terminals B and A (wiring harness-side). • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to each other, then go to Step 11.
8		No	Go to the next step.
9	INSPECT CKP SENSOR CIRCUIT FOR OPEN CIRCUIT • CKP sensor and PCM connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side): ― CKP sensor terminal B—PCM terminal 2W ― CKP sensor terminal A—PCM terminal 2P • Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 11.
10	INSPECT CKP SENSOR • Inspect the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [MZR 2.3 DISI Turbo].) • Is there any malfunction?	Yes	Replace the CKP sensor, then go to the next step. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)
10		No	Go to the next step.
11	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR 2.3 DISI Turbo].) • Perform the KOER self test. (See KOEO/KOER SELF TEST [MZR 2.3 DISI Turbo].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].) Go to the next step.
11		No	Go to the next step.
12	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR 2.3 DISI Turbo].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR 2.3 DISI Turbo].)
12		No	DTC troubleshooting completed.
