id0102h9703000

DTC P0327:00

KS circuit low input

DETECTION CONDITION

•  The PCM monitors input signal from the KS. If the input voltage is low for 5 s, the PCM determines that the KS circuit has a malfunction.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

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

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

•  Sets the knocking spark retard correction value of the ignition control to the fixed value.

POSSIBLE CAUSE

•  KS connector or terminals malfunction

•  KS malfunction

•  Short to ground in wiring harness between the following terminals:

―  KS terminal A—PCM terminal 1H

―  KS terminal B—PCM terminal 1D

•  PCM connector or terminals malfunction

•  KS circuits are shorted to each other

•  Open circuit in wiring harness between the following terminals:

―  KS terminal A—PCM terminal 1H

―  KS terminal B—PCM terminal 1D

•  PCM malfunction

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 KS CONNECTOR CONDITION • Switch the ignition off. • Disconnect the KS connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 9.
3		No	Go to the next step.
4	INSPECT KS • Inspect the KS. (See KNOCK SENSOR (KS) INSPECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Is there any malfunction?	Yes	Replace the KS, then go to Step 9. (See KNOCK SENSOR (KS) REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
4		No	Go to the next step.
5	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 and/or terminals, then go to Step 9.
5		No	Go to the next step.
6	INSPECT KS CIRCUIT FOR SHORT TO GROUND • Verify that the KS connector is disconnected. • Inspect for continuity between the following terminals (wiring harness-side) and body ground: ― KS terminal A ― KS 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: • KS terminal A—PCM terminal 1H • KS terminal B—PCM terminal 1D 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 9.
6		No	Go to the next step.
7	INSPECT KS CIRCUITS FOR SHORT TO EACH OTHER • Verify that the KS and PCM connectors are disconnected. • Inspect for continuity between KS terminals A and B (wiring harness-side). • Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • KS terminal A—PCM terminal 1H • KS terminal B—PCM terminal 1D 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 each other. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to each other. Go to Step 9.
7		No	Go to the next step.
8	INSPECT KS CIRCUIT FOR OPEN CIRCUIT • Verify that the KS and PCM connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side): ― KS terminal A—PCM terminal 1H ― KS terminal B—PCM terminal 1D • Is there continuity?	Yes	Go to the next step.
8		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • KS terminal A—PCM terminal 1H • KS terminal B—PCM terminal 1D 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 an open circuit. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has an open circuit. Go to the next step.
9	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) Go to the next step.
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
10		No	DTC troubleshooting completed.
