2.2.7.19 DTC P0112 P0113 1. DTC description: DTC P0112 Intake Air Temperature Sensor Circuit Low Voltage
DTC P0113 Intake Air Temperature Sensor Circuit High Voltage or Open Circuit Intake air temperature pressure sensor has a signal circuit and an ECM internal ground circuit. 2. Conditions For Setting DTC and The Fault Location: DTC Code DTC Detection Strategy Conditions For Setting The Fault Locations 1. MAT circuit is short to ground. 2. MAT signal voltage becomes 0 immediately. P0112 P0113 1. More Than the Upper Limit 2. Lower Than the Lower Limit 1. MAT circuit is open or short to 5 V reference 1. Sensor Circuit 2. Sensor 3. ECM. 3. Circuit sketch Circuit diagram refers to 2.2.7.18 Circuit Diagram in DTC P0107 P0108. 4. Diagnostic Steps: Note: Before carrying out this diagnosis step, observe the data list on fault diagnosis tester and Step 1 Initial Inspection Inspect if there are the following conditions: (a) Sensor housing is damaged. (b) Sensor loose or improperly installed. (c) Sensor wiring harness connector loose. It is not allowed to connect 5 V reference voltage circuit of intake manifold absolute pressure
Step 2 Measure intake air pressure and temperature sensor resistance. Next 175 |
