Pinpoint Test N: Shift Solenoid B

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

N1 RETRIEVE AND RECORD ALL DTCS
- Using the diagnostic scan tool, retrieve all DTCs.
Are DTCs P0755, P0758, P0759, P0976 and/or P0977 present?
- Yes : For DTCs P0755, P0758 and/or P0759, GO to N2 .
  For DTC P0976, GO to N4.
  
  For DTC P0977, GO to N6.
- No : GO to SYMPTOM CHART .

N2 CHECK THE SSB CIRCUIT FOR AN OPEN

Ignition OFF.
Disconnect: Transmission Vehicle Harness C168 .
Disconnect: PCM C1551E .
Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.

Measure the resistance between.

Is the resistance between 4.0 and 7.2 ohms?

Yes : INSTALL a new PCM. REFER to the appropriate PCM in REMOVAL AND INSTALLATION . PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD .
No : REMOVE the main control cover. REFER to MAIN CONTROL COVER - 3.5L GTDI . INSPECT the solenoid body for metal shavings on the exposed metal contacts or other components. CLEAN the solenoid body and RECHECK the resistance value. If the resistance value is out of specification and a short to ground is not found, INSTALL a new solenoid body assembly. REFER to SOLENOID BODY ASSEMBLY . PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD .

N4 CHECK THE SSB CIRCUIT FOR A SHORT TO GROUND

Ignition OFF.
Disconnect: Transmission Vehicle Harness C168 .
Disconnect: PCM C1551E .
Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.

Measure the resistance between.

Is the resistance less than 3 ohms?

Yes : REMOVE the main control cover. REFER to MAIN CONTROL COVER - 3.5L GTDI . INSPECT the solenoid body for metal shavings on the exposed metal contacts or other components. CLEAN the solenoid body and RECHECK the resistance value. If the resistance value is out of specification and a short to ground is not found, INSTALL a new solenoid body assembly. REFER to SOLENOID BODY ASSEMBLY . PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD .
No : INSTALL a new PCM. REFER to the appropriate PCM in REMOVAL AND INSTALLATION . PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD .

N6 CHECK THE SSB CIRCUIT FOR A SHORT TO VOLTAGE

Ignition OFF.
Disconnect: Transmission Vehicle Harness C168 .
Disconnect: PCM C1551E .
Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
Ignition ON.

Measure the voltage between.
