Fig. 186: Manifold Absolute Pressure (MAP) Sensor Normal Operation And System Failure - 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 (idling) and high signal voltage 
at low-vacuum (throttle valve wide open). 

The engine control module (ECM)/powertrain control module (PCM) compares a predetermined MAP value at 
a given throttle position and manifold absolute pressure to the output voltage value of the MAP sensor. 

If the MAP sensor outputs lower voltage than expected, the ECM/PCM detects a malfunction and stores a DTC.

ENABLE CONDITIONS 

Malfunction Threshold 

The MAP sensor output is 28 kPa (8.4 in.Hg, 215 mmHg)* or less for at least 2 seconds when atmospheric 
pressure is 52 kPa (15.4 in.Hg, 392 mmHg). 

*: Depending on atmospheric pressure. 

Driving Pattern 

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator 

fan comes on.  

2. Drive the vehicle at a speed of 15 mph (24 km/h) or more with a throttle position as specified under 

Enable Conditions for at least 2 seconds.  



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM 
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the 
freeze frame data are stored. 

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

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). 

The engine control module (ECM)/powertrain control module (PCM) compares a predetermined MAP value at 
a given throttle position and manifold absolute pressure to the output voltage value of the MAP sensor. 

If the MAP sensor outputs high voltage during fuel cut-off operation for deceleration with the throttle valve 
fully closed, which should make the manifold absolute pressure lower, the ECM/PCM detects a malfunction 
and stores a DTC.
