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

    -3. Test-drive under these conditions:

    • Engine coolant temperature (ECT SENSOR 1) above 158 deg. F (70 deg. C)
    • Engine speed at 1, 400 rpm or more

    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.
