Code P1112 Volvo Description
The P1112 diagnostic trouble code (DTC) for Volvo vehicles indicates that the outside temperature sensor signal is either too low or too high. This sensor is responsible for measuring the ambient temperature outside the vehicle and sending this information to the engine control module (ECM). The ECM uses this data to make adjustments to various systems in the vehicle, such as the fuel injection, ignition timing, and emissions control. When the sensor signal is outside the expected range, it can lead to issues with the vehicle's performance and overall functionality.
Common Causes of P1112 Volvo
- Faulty outside temperature sensor
- Wiring issues or poor connections in the sensor circuit
- Corrosion or damage to the sensor
- Software glitches in the ECM
- Extreme temperature fluctuations affecting sensor readings
Symptoms of P1112 Volvo
- Inaccurate temperature readings on the dashboard display
- Engine running too rich or too lean
- Poor fuel economy
- Rough idling or stalling
- Illumination of the check engine light
How to Fix P1112 Volvo
- Begin by diagnosing the issue using a scan tool to retrieve the specific DTC and confirm the outside temperature sensor signal is out of range.
