Volvo models this fault code applies to
Applies to the following models:
5 modelsC70 Cabriolet (1998–2005), C70 Coupé (1998–2002), S70 (1997–2000), V70 (1997–2000), V70 XC (1998–2000)
What does this fault code mean?
The outside temperature sensor sends an incorrect signal to the instrument panel, so the outside temperature is not shown correctly or not at all. The fault is intermittent, meaning it has occurred before but does not always show. The causes may be poor contact, an open circuit in the signal wire, a short to ground or voltage, or a faulty sensor.
Possible causes
- Contact resistance in the connections
- Signal wire shorted to ground or voltage
- Open circuit in the signal wire
- Faulty outside temperature sensor
What you can do
- 1Read off the fault code, note it and clear it. Test drive the vehicle to see if the fault returns
- 2Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 3Check the sensor and instrument connectors for oxidation and loose fit
- 4Use a multimeter to confirm the signal wire to the sensor has no contact with ground (body) or voltage
- 5If you have a diagnostic tool, read the sensor value in live data. If the value is missing or unrealistic, the sensor or the wire is at fault
- 6If the fault remains, have a workshop replace the sensor once the wire has been checked
Symptoms you may notice1
- The outside temperature display shows no value
