Vehicle applicability: This diagnostic supplement covers multiple Ford vehicles and engines. Follow the application named in the source below. Some references apply to vehicles other than Mustang.
DV9 CHECK THE TP CIRCUITS FOR A SHORT TOGETHER
• Measure the resistance between:
( + ) ETBTPS Connector, Harness Side | ( - ) ETBTPS Connector, Harness Side |
|---|---|
TP1 | TP2 |
TP1 | ETCREF |
TP1 | ETCRTN |
TP2 | ETCREF |
TP2 | ETCRTN |
Are the resistances greater than 10K ohms?
Yes | No |
|---|---|
GO to DV10 . | REPAIR the short circuit. Clear the PCM DTCs. REPEAT the self-test. |
DV10 CHECK THE TP1 AND TP2 CIRCUITS FOR A SHORT TO VOLTAGE
• Ignition ON, engine OFF.
• Measure the voltage between:
( + ) ETBTPS Connector, Harness Side | ( - ) |
|---|---|
TP1 | Ground |
TP2 | Ground |
Is any voltage present?
Yes | No |
|---|---|
REPAIR the short circuit. Clear the PCM DTCs. REPEAT the self-test. | GO to DV11 . |
DV11 CHECK THE THROTTLE POSITION (TP) OPEN AND CLOSED VOLTAGES
Note: Certain failure mode effects management (FMEM) operating strategies maintain limited vehicle function in the event of a PCM, harness, or component concern and may prevent the throttle plate from opening. If the throttle plate does not open, follow the NO answer.
Note: Make sure the accelerator pedal is not applied during the fully released voltage measurements.
• Ignition OFF.
