| P2074 MAP Sensor Signal Lower Than Expected |
DTC (PGM-FI)
- 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
NO
Go to step 2.
- MAP sensor performance check 2
-1. Note the value of MAP Sensor 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 in the DATA LIST with the HDS.
Signal Current conditions Values Unit MAP Sensor (Hi Res) Does the MAP Sensor change 0.67 kPa (0.2 inHg, 5 mmHg) or more?
YES
Go to step 3.
NO
- Problem verification
-1. Clear the DTC with the HDS.
-2. Start the engine. Hold the engine speed at 3, 000 rpm without load (in P or N) until the radiator fan comes on.
-3. Test-drive the vehicle under these conditions:
- Engine speed at 1, 700 rpm or more
- Transmission in D
- REL TP SENSOR above 42.2 deg
- Drive 5 seconds or more
Signal Current conditions 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.
