The manifold absolute pressure (MAP) sensor, barometric pressure (BARO) sensor, and leak detection module absolute pressure sensor all measure BARO when the engine is stopped. All three sensor outputs are compared to detect malfunction. If all three sensors are within an acceptable range of each other, then conditions are normal. If any of the three sensors are out of range, then the out of range sensor is judged as abnormal. When a DTC is set, use these values to determine the abnormal sensor. When the engine is running, the sensor value from the MAP sensor is compared to the estimated manifold absolute pressure (based on engine speed, and the sensor value from the Throttle Position Sensor (TPS)), as well as the BARO sensor. If any of these three values are out of range, the powertrain control module (PCM) detects a malfunction and stores a DTC.

Malfunction Threshold 

• Detection during engine stop

  Turn the vehicle to the ON mode or an engine stop, the malfunction is detected by comparing information from the MAP sensor, BARO sensor and leak detection module absolute pressure sensor.

Pressure difference between each sensor values		Malfunction judgment
MAP sensor - BARO sensor	Leak check module absolute pressure sensor - BARO sensor	MAP sensor	BARO sensor	Leak check module absolute pressure sensor
Higher than 17 kPa (5 inHg, 125 mmHg)	Higher than 17 kPa (5 inHg, 125 mmHg)	Normal	Failure	Normal
	From -16 kPa (-4.9 inHg, -125 mmHg) to 16 kPa (4.9 inHg, 125 mmHg)	Failure	Normal	Normal
	Lower than -16 kPa (-4.9 inHg, -125 mmHg)	Failure	Normal	Failure

• Detection with the engine running

  When the measurement by the MAP sensor is out of the normal range for the measurement by the TP sensor for 4.1 seconds or more.

Possible Cause 

Confirmation Procedure 

Operating Condition 

1. Turn the vehicle to the ON mode, and wait 4.1 seconds.
2. Enter the maintenance mode, then start the engine. Hold the engine speed [Engine Speed] at 3, 000 RPM without load (in P or N) until the radiator fan comes on.
3. Engine speed [Engine Speed] at 1, 100 RPM or more (in N) for at least 5 seconds.
4. Drive immediately at a steady speed of 40 mph (60 km/h) or more and engine speed [Engine Speed] between 1, 100 - 5, 500 RPM for at least 5 seconds.

• When freeze data is stored, drive the vehicle under those conditions instead of Driving Pattern step 4
• Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

With the HDS 

None.

Diagnosis Details 

Conditions for setting the DTC 

When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC 

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
