DTC Troubleshooting (cont'd)
6. While holding the engine speed at 2,500 rpm, check
the MAF SENSOR in the DATA LIST with the HDS.
Is there about 5.6 7 .8 gm/ s ( M/ T ) or 6.5
9.1 gm/ s ( A/ T )?
YES − Check the engine valve clearances, and
adjust them if necessary (see page 6-9). If the valve
clearances are OK, replace the injectors (see page
11-223), then go to step 7.
NO − Replace the MAF sensor/IAT sensor (see page
11-227), then go to step 7.
7. Turn the ignition switch to ON (II).
8. Reset the ECM/PCM with the HDS.
9. Do the ECM/PCM idle learn procedure (see page
11-343).
10. Start the engine. Hold the engine speed at
3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, then let it
idle.
11. Test-drive under these conditions:
• Engine coolant temperature (ECT SENSOR 1)
above 158 °F (70 °C)
• A/T in D, M/T in 4th
• Drive at a steady speed between 15 75 mph
−
(24 120 km/h) for 15 minutes
NOTE: DTC P0171 and/or P0172 may take up to
80 minutes of test driving to set. Using the HDS,
monitor the air fuel feed back average (AF FB AVE).
If the AF FB AVE stays within 0.80 1.25, there is no
problem at this time.
12. Check for Temporary DTCs or DTCs with the HDS.
Is DT C P017 1 or P017 2 indicated?
−
YES Go to step 1.
NO − Troubleshooting is complete. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC's troubleshooting.
