A/C Pressure Sensor Circuit, Short to B+







Fault symptom
- No cooling.
- No A/C function.

On-board diagnosis

Type of diagnosis:
- Continuous

Enable criteria:
- Battery voltage must be between 11 - 16 V.
- Engine running.
- Outdoor temperature higher than -7 degree C.

Fault criteria:
- When input voltage exceeds 4.2 V for more than 1 s.

Dependent:
- None

System reaction to a fault:
- The control module deactivates the output to the A/C relay.

OK report:
- Fault criteria NOT fulfilled for 2 s.

Fault handling:
- Type III without Check Engine.
(See section Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness
- Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
