DTC 12

CONTROL LEVER POSITION SENSOR MALFUNCTION
DETECTION CONDITION
•  Input voltage from control lever position sensor is below 0.1 V or above 4.75 V when continued for 1.0 S.
•  When idle switch is on, input voltage from control lever position sensor is below 0.35 V or above 1.39 V.
POSSIBLE CAUSE

•  Idle switch malfunction
•  Open circuit in wiring from control lever position sensor (FIP connector: 8 pin) terminal C to PCM terminal B
•  Open or short circuit in wiring from control lever position sensor (FIP connector: 8 pin) terminal A to PCM terminal J
•  Open or short circuit in wiring from control lever position sensor (FIP connector: 8 pin) terminal B to PCM terminal A
•  Open or short circuit in wiring from idle switch (FIP connector: 8 pin) terminal E to PCM terminal H

Diagnostic procedure

STEP

INSPECTION

ACTION
1
Does control lever position sensor connector or PCM connector have poor connection?
Yes
Repair or replace connector, then go to Step 7.
No
Go to the next step.
2
Disconnect control lever position sensor connector.
Turn engine switch on.
