DTC P0330:00 [MZI-3.7]

id0102d2313200

DTC P0330:00 | KS circuit (LH)
--- | ---
DETECTION CONDITION | • The KS detects vibrations upon increase and decrease in engine RPM. The KS generates a voltage based on this vibration. A DTC is set if the voltage goes outside a calibrated level.
POSSIBLE CAUSE | • Connector or terminal malfunction • Short to power supply in wiring harness between KS terminal A and PCM terminal 2AH • Short to power supply in wiring harness between KS terminal B and PCM terminal 2AD • Short to ground circuit between KS terminal A and PCM terminal 2AH • Short to ground circuit between KS terminal B and PCM terminal 2AD • Open circuit wiring harness between KS terminal A and PCM terminal 2AH • Open circuit wiring harness between KS terminal B and PCM terminal 2AD • KS 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.
No | Record FREEZE FRAME 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.
No | Go to the next step.
3 | INSPECT KS CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the KS connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are there any malfunction? | Yes | Repair or replace suspected part, then go to Step 9.
No | Go to the next step.
4 | INSPECT KS (LH) SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • KS connector is disconnected. • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between the following terminals: ― KS terminal A (wiring harness-side) and body ground. ― KS terminal B (wiring harness-side) and body ground. • Are there voltage B+? | Yes | Repair or replace suspected part, then go to Step 9.
No | Go to the next step.
5 | INSPECT KS (LH) CIRCUIT FOR SHORT TO GROUND • KS connector is disconnected. • Turn the ignition switch to off. • Inspect for continuity between the following terminals: ― KS terminal A (wiring harness-side) and body ground. ― KS terminal B (wiring harness-side) and body ground. • Are there continuity? | Yes | Repair or replace suspected part, then go to Step 9.
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). • Are there any malfunction? | Yes | Repair or replace suspected part, then go to Step 9.
No | Go to the next step.
7 | INSPECT KS (LH) CIRCUIT FOR OPEN CIRCUIT • KS and PCM connectors are disconnected. • Turn the ignition switch off. • Inspect for continuity between the following terminals: ― KS terminal A (wiring harness-side) and PCM terminal 2AH (wiring harness-side) ― KS terminal B (wiring harness-side) and PCM terminal 2AD (wiring harness-side) • Are there continuity? | Yes | Go to the next step.
No | Repair or replace suspected part, then go to Step 9.
8 | INSPECT THE KS (LH) • Inspect the KS (LH). (See KNOCK SENSOR (KS) INSPECTION [MZI-3.7].) • Is there malfunction? | Yes | Replace the KS, then go to the next step. (See KNOCK SENSOR (KS) REMOVAL/INSTALLATION [MZI-3.7].)
No | Go to the next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0330:00 HAS BEEN COMPLETED • Verify that all disconnected connectors reconnected. • Clear the DTC from the PCM memory using the M-MDS. • Perform the KOEO or KOER self-test. (See KOEO/KOER SELF TEST [MZI-3.7].) • Is the PENDING CODE for the DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
