DTC P0107 (3): ADVANCED DIAGNOSTICS 

DTC P0107: MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR CIRCUIT LOW VOLTAGE 

Fig. 1: Manifold Absolute Pressure (MAP) Sensor (Low Voltage) - Circuit Diagram 

Fig. 2: Manifold Absolute Pressure (MAP) Sensor Output Voltage Graph 

General Description 

The manifold absolute pressure (MAP) sensor senses manifold absolute pressure (vacuum) and converts it 
into electrical signals. The MAP sensor outputs low signal voltage at high-vacuum (throttle valve closed) 
and high signal voltage at low-vacuum (throttle valve wide open). 

If a signal voltage from the MAP sensor is a set value or less, the powertrain control module (PCM) detects 
a malfunction and a DTC is stored.

MONITOR DESCRIPTION CHART 

Enable Conditions 

ENABLE CONDITIONS 

Malfunction Threshold 

The MAP sensor output voltage is 0.23 V or less for at least 2 seconds. 

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the 
PCM memory. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the 
diagnostic runs. 

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by 
disconnecting the battery.

DTC P0111 (10): ADVANCED DIAGNOSTICS 

DTC P0111: INTAKE AIR TEMPERATURE (IAT) SENSOR CIRCUIT RANGE/PERFORMANCE 
PROBLEM 

Fig. 5: Intake Air Temperature (IAT) Sensor Performance Graph 

General Description 

Two engine coolant temperature sensors and one intake air temperature sensor are used by the powertrain 
control module (PCM). 

When the engine is stopped and enough time has passed, the temperature of the engine will equal the 
ambient temperature. When an inappropriate temperature is detected after comparing the temperature 
readings of each sensor, a malfunction in the corresponding sensor is detected and a DTC is stored.
