Status check
Check if the outside temperature gauge display is outside its permitted range.
Does the outside temperature gauge display a value outside its permitted range?
Yes - Checking components and wiring
No - Checking components and wiring
-------------------------------------------------
Checking components and wiring
Hint: If the cable and the combined instrument panel are fault free the voltage between terminals 1 and 2 on the outside temperature sensor connector should be approximately 5 V.
Check outside temperature sensor connector for contact resistance and oxidation according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
Check the signal cable between the outside temperature gauge terminal 1 and the combined instrument panel terminal A19 (#A19) for a short-circuit to voltage according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault , and an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
Check the ground lead between the outside temperature gauge terminal 2 and the combined instrument panel terminal A12 (#A12) for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault , and an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
Remedy as necessary.

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off.
- Reinstall the connectors, components etc.
Check that the outside temperature sensor display is within its permitted range.
Does the outside temperature sensor display values within their permitted range?
Yes - VERIFIED
