DTC P0112: Intake Air Temperature Sensor Circuit - Low Input: Condition
WARNING: This page is about a different car, the 2002 Suzuki Esteem. However, it is still accessible from the selected car via links, so may be relevant.
DTC is set when Engine Control Module (ECM) detects low Intake Air Temperature (IAT) voltage after engine is at operating temperature. MIL is illuminated when ECM detects malfunction during first drive cycle. Possible causes are:
- Short to ground in circuit between IAT and ECM.
- IAT sensor malfunction.
- ECM malfunction.
