DG1 DETERMINE THE DIAGNOSTIC TROUBLE CODE (DTC) BEING DIAGNOSED

Is DTC P0325 present in the KOEO or KOER self-test?

Yes	No
GO to DG2.	GO to DG10.

DG2 CHECK THE RESISTANCE OF THE KS1

Verify the KS is connected and properly installed.
KS connector disconnected.
Measure the resistance between:

(+) KS Connector, Component Side	(-) KS Connector, Component Side
KS1+ - Pin 2	KS1- - Pin 1

Is the resistance between 4.39 - 5.35 Mohms?

Yes	No
GO to DG3.	INSTALL a new KS. REFER to ELECTRONIC ENGINE CONTROLS . CLEAR the DTCs. REPEAT the self-test.

DG3 CHECK THE KS1+ CIRCUIT FOR A SHORT TO VOLTAGE IN THE HARNESS

Key ON, engine OFF.
Measure the voltage between:

(+) KS Connector, Harness Side	(-) Vehicle Battery
KS1+ - Pin 2	Negative terminal

Is the voltage less than 1 V?

Yes	No
GO to DG4.	REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test.

DG4 CHECK THE KS1- CIRCUIT FOR A SHORT TO VOLTAGE IN THE HARNESS

Measure the voltage between:

(+) KS Connector, Harness Side	(-) Vehicle Battery
KS1- - Pin 1	Negative terminal

Is the voltage less than 1 V?

Yes	No
GO to DG5.	REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test.

DG5 CHECK THE KS1+ CIRCUIT FOR AN OPEN IN THE HARNESS

Key in OFF position.
PCM connector disconnected.
Measure the resistance between:

(+) KS Connector, Harness Side	(-) PCM Connector, Harness Side
KS1+ - Pin 2	KS1+ - Pin E46

Is the resistance less than 5 ohms?

Yes	No
GO to DG6.	REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

DG6 CHECK THE KS1+ CIRCUIT FOR A SHORT TO GROUND IN THE HARNESS

Measure the resistance between:

(+) KS Connector, Harness Side	(-) Vehicle Battery
KS1+ - Pin 2	Negative terminal

Is the resistance greater than 10K ohms?

Yes	No
GO to DG7.	REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test.

DG7 CHECK THE KS1- CIRCUIT FOR AN OPEN IN THE HARNESS

Measure the resistance between:

(+) KS Connector, Harness Side	(-) PCM Connector, Harness Side
KS1- - Pin 1	KS1- - Pin E47

Is the resistance less than 5 ohms?

Yes	No
GO to DG8.	REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

DG8 CHECK THE KS1- CIRCUIT FOR A SHORT TO GND IN THE HARNESS

Measure the resistance between:

(+) KS Connector, Harness Side	(-) Vehicle Battery
KS1- - Pin 1	Negative terminal

Is the resistance greater than 10K ohms?

Yes	No
GO to DG9.	REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test.

DG9 CHECK FOR KS HARNESS CIRCUITS SHORTED TOGETHER

Measure the resistance between:

(+) KS Connector, Harness Side	(-) KS Connector, Harness Side
KS1+ - Pin 2	KS1- - Pin 1

Is the resistance greater than 10K ohms?

Yes	No
GO to DG11.	REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test.

DG10 CHECK THE KS CIRCUIT(S) FOR INTERMITTENT CONCERNS

Check for short to PWR, short to GND, or open KS1+ and KS1- circuit(s) while carrying out a wiggle test on all accessible wiring and connectors associated with the KS.

Is a concern present during the wiggle test?

Yes	No
REPAIR as necessary. CLEAR the DTCs. REPEAT the self-test.	No concern present. The problem may be intermittent. GO to PINPOINT TEST Z .

DG11 CHECK FOR CORRECT PCM OPERATION

Disconnect all the PCM connectors.
Visually inspect for:
- pushed out pins
- corrosion
Connect all the PCM connectors and make sure they seat correctly.
Carry out the PCM self-test and verify the concern is still present.

Is the concern still present?

Yes	No
INSTALL a new PCM. REFER to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) .	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
