DTC Troubleshooting (cont’d)

MAP Sensor Circuit Lower Than

Expected
(2005-2006 models)

NOTE: Information marked with an asterisk ( ) applies
to K20Z1 engine.

1. Turn the ignition switch ON (II).

2. Check the MAP SENSOR in the DATA LIST with the

HDS.

Go to step 7.

Go to step 3.

3. Clear the DTC with the HDS.

4. Start the engine. Hold the engine speed at

3,000 rpm without load (in Park or neutral) until the
radiator fan comes on, then let it idle.

5. Test-drive under these conditions:

• Engine coolant temperature above 158 °F (70 °C)
• Engine speed between 1,050 (1,300) and 6,700

(7,800) rpm

• A/T in D position (M/T in 3rd gear)
• Vehicle speed above 15 mph (24 km/h)
• Engine speed between 1,000 and 4,000 rpm for

2 seconds or more

6. Monitor the OBD STATUS for DTC P1128 in the

DTCs MENU with the HDS.

Go to step 7.

If the screen indicates PASSED, intermittent

failure, system is OK at this time. Check for poor
connections or loose terminals at the MAP sensor
and the ECM/PCM. If the screen indicates NOT
COMPLETED, go to step 4 and recheck.

7. Turn the ignition switch OFF.

8. Replace the MAP sensor (see page 11-412).

9. Turn the ignition switch ON (II).

10. Reset the ECM/PCM with the HDS.

11. Do the ECM/PCM idle learn procedure (see page

11-349).

12. Start the engine. Hold the engine speed at

3,000 rpm without load (in Park or neutral) until the
radiator fan comes on, then let it idle.

13. Test-drive under these conditions:

• Engine coolant temperature above 158 °F (70 °C)
• Engine speed between 1,050 (1,300) and 6,700

(7,800) rpm

• A/T in D position (M/T in 3rd gear)
• Vehicle speed above 15 mph (24 km/h)
• Engine speed between 1,000 and 4,000 rpm for

2 seconds or more

14. Check for Temporary DTCs or DTCs with the HDS.

If DTC P1128 is indicated, check for poor

connections or loose terminals at the MAP sensor
and the ECM/PCM, then go to step 1. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

Go to step 15.

15. Monitor the OBD STATUS for DTC P1128 in the

DTCs MENU with the HDS.

Troubleshooting is complete.

If the screen indicates FAILED, check for poor

connections or loose terminals at the MAP sensor
and the ECM/PCM, then go to step 1. If the screen
indicates NOT COMPLETED, go to step 12 and
recheck.

Is less than 54.1 kPa ( 16.0 in.Hg, 406 mmHg) or
1.61 V held f or mor e than 5 seconds?

Does the scr een indicate F AILED?

Ar e any T empor ar y DT Cs or DT Cs indicated?

• Intake manifold
• Brake booster hose

Go to step 2.

Repair or replace parts with vacuum leaks,

then go to step 9.

2. Start the engine. Hold the engine speed at

3,000 rpm without load (in Park or neutral) until the
radiator fan comes on, then let it idle.

3. Check the MAP SENSOR in the DATA LIST with the
