DTC P2074 (1.5 L Engine)

DTC P2074  : MAP Sensor Signal Lower Than Expected

NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (PGM-FI)

1. MAP sensor performance check 1

   -1. Turn the vehicle to the ON mode.

   -2. Compare the value of the parameter (s) below with the HDS.

   Signal	Current conditions
   	Values	Unit
   MAP Sensor (Hi Res)
   TC Boost Pressure

   Does the value differ more than 26.7 kPa (7.9 inHg, 200 mmHg)?

   YES 

   Replace the MAP sensor .

   NO 

   Go to step 2.

2. MAP sensor performance check 2

   -1. Note the value of MAP Sensor (Hi Res) in the DATA LIST with the HDS.

   Signal	Current conditions
   	Values	Unit
   MAP Sensor (Hi Res)

   -2. Start the engine and let it idle.

   -3. Check the MAP Sensor (Hi Res) in the DATA LIST with the HDS.

   Signal	Current conditions
   	Values	Unit
   MAP Sensor (Hi Res)

   Does the MAP Sensor (Hi Res) change 0.67 kPa (0.2 inHg, 5 mmHg) or more?

   YES 

   Go to step 3.

   NO 

   Replace the MAP sensor .

3. 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 for at least 5 seconds.

   Test-drive the vehicle under these conditions:

   • Engine speed at 1, 700 rpm or more
   • CVT in D, M/T in 4th or 5th
   • REL TP Sensor above 42.2 deg
   • Drive 6 seconds or more

   	Values	Unit
   Engine Speed
   REL TP Sensor

   -4. 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 on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot . If the HDS indicates NOT COMPLETED, go to step 3-2 and recheck.
