5. Repair Instructions:
Replace the MAP sensor. Refer to
Refer to 2.2.8.8 Engine Control Module
2.2.7.18 DTC P0112 P0113
1. DTC Descriptor:
DTC P0112
DTC P0113
The sensor is an integrated part of the engine intake pressure sensor for Measure the temperature of air entering the engine. ECM
provides 5 V reference voltage through ECM harness connector EN01 terminal No.25 to the intake air pressure and temperature
sensor wiring harness connector EN16 terminal No.2. At the same time it provides ECM internal low reference voltage through EN01
terminal No.40 to intake air pressure and temperature sensor EN16 terminal No.1. When the intake air pressure and temperature
sensors is cold, the thermistor value used to measure temperature is high. When the air temperature rises, the resistance decreases.
When the resistance is higher, ECM will detect the signal circuit with a higher voltage. With the decrease of resistance, ECM detected
intake air temperature signal circuit voltage also decreases.

ReplacementReplace ECM.
Intake Air Temperature Sensor Signal Voltage Too Low
Intake Air Temperature Sensor Signal Voltage Too High
Conditions For Setting The DTC (Control Strategy)
1. Short to ground. Intake air temperature is higher than
138°C (280.4 ºF).
2. Short to power supply. Intake air temperature is less than
-38.3°C (-36.9 ºF).
3. Startup time more than 240 s.
4. Engine idle.
