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.
DN: Pressure And Temperature Sensors
DN: Introduction
DN1 CHECK FOR DTCS
Note: This pinpoint test is designed to diagnose multiple components in the same test steps, only measure the circuits that apply to the vehicle and the component being diagnosed.
Note: Diagnose circuit concerns before range or performance concerns.
Are DTCs P007B, P007C, P007D, P0096, P0097, P0098, or P00CE present?
Yes | No |
|---|---|
GO to DN2 . | For symptoms without DTCs, GO to DN2 . For all others, RETURN to Section 3 , Symptom Charts for further direction. |
DN2 MONITOR THE PID
• Ignition ON, engine OFF.
• For the IAT2 or MAP/IAT2 sensor,
• Access the PCM and monitor the IAT2 (VOLT) PID.
• For the MAP/CACT or TCBP/CACT sensor,
• Access the PCM and monitor the CAC_V (VOLT) PID.
Are the voltages between 0.5 - 4.95 V?
Yes | No |
|---|---|
GO to DN6 . | GO to DN3 . |
DN3 CHECK THE CIRCUITS FOR AN OPEN
• Ignition OFF.
• PCM connector disconnected.
• For the IAT2 sensor,
• IAT2 Sensor connector disconnected.
• Measure the resistance between:
( + ) IAT2 Sensor Connector, Harness Side | ( - ) PCM Connector, Harness Side |
|---|---|
IAT2 - Pin 1 | IAT2 |
SIGRTN - Pin 2 | SIGRTN |
• For the MAP/CACT sensor,
• MAP/CACT Sensor connector disconnected.
• Measure the resistance between:
