DTC P0332 [13B-MSP]

DTC REFERENCE CHART

DTC P0332

KS No. 2 circuit low input

DETECTION CONDITION

The PCM monitors the input voltage from the KS No. 2 when the engine is running. If the input voltage is less than 1.2 V , the PCM determines that the KS No. 2 circuit input voltage is low.

Diagnostic support note

This is a continuous monitor (CCM.)
The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
FREEZE FRAME DATA is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

Connector or terminal malfunction
Short to ground in wiring harness between KS No. 2 terminal A and PCM terminal 2AC
Short to ground in wiring harness between KS No. 2 terminal B and PCM terminal 2Y
KS No. 2 malfunction
Open circuit in wiring harness between KS No. 2 terminal A and PCM terminal 2AC
Open circuit in wiring harness between KS No. 2 terminal B and PCM terminal 2Y
PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT KS NO. 2 CONNECTOR FOR POOR CONNECTION Turn the ignition switch off. Disconnect the KS No. 2 connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion.) Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
3		No	Go to the next step.
4	INSPECT KS NO. 2 CIRCUIT FOR SHORT TO GROUND Turn the ignition switch off. Inspect for continuity between the following circuits: KS No. 2 terminal A (wiring harness-side) and body ground KS No. 2 terminal B (wiring harness-side) and body ground Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 8.
4		No	Go to the next step.
5	INSPECT KS NO. 2 Inspect the KS No. 2. (See KNOCK SENSOR (KS) INSPECTION [13B-MSP] .) Is there any malfunction?	Yes	Replace the KS No. 2, then go to Step 8. (See KNOCK SENSOR (KS) REMOVAL/INSTALLATION [13B-MSP] .)
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR FOR POOR CONNECTION Turn the ignition switch off. Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion.) Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
6		No	Go to the next step.
7	INSPECT KS NO. 2 CIRCUIT FOR OPEN CIRCUIT Turn the ignition switch off. Inspect for continuity between the following circuits: KS No. 2 terminal A (wiring harness-side) and PCM terminal 2AC (wiring harness-side) KS No. 2 terminal B (wiring harness-side) and PCM terminal 2Y (wiring harness-side) Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0332 COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. Start the engine. Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [13B-MSP] .)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [13B-MSP] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [13B-MSP] .)
9		No	DTC troubleshooting completed.
