P2074 MAP Sensor Signal Lower Than Expected

MAP sensor performance check:

MAP sensor performance check

?1.	Turn the vehicle to the ON mode.

?2.

Check the parameter(s) below with the HDS.

Signal	Threshold		Current conditions
Signal	Values	Unit	Values	Unit
MAP SENSOR	Less than 54.1	kPa
MAP SENSOR	Less than 406.0	mmHg

Did the value maintain the malfunction threshold for 5 seconds or more?


	YES

Replace the MAP sensor.?


	NO

Go to step 2.

Problem verification:

Problem verification

?1.	Clear the DTC with the HDS.

?2.	Start the engine. Hold the engine speed at 3,000 rpm without load (CVT in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.

?3.

Test-drive under these conditions:

	Engine coolant temperature (ECT SENSOR 1) above 158 °F (70 °C)
	Engine speed at 1,400 rpm or more
	CVT in D, M/T in 5th or 6th
	Drive at a steady speed at 15 mph (24 km/h) for 2 seconds or more with under half throttle

Monitor the OBD STATUS for DTC P2074 in the DTCs MENU with the HDS.

DTC Description	OBD STATUS
P2074 MAP Sensor Signal Lower Than Expected

Does the HDS indicate FAILED?


	YES

The failure is duplicated. Replace the MAP sensor.?


	NO

If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot. If the HDS indicates NOT COMPLETED, go to step 2-2 and recheck.?
