NOTE: If the oil pressure warning indicator stays on
with the engine running, check the engine oil l
evel. If
the oil level is correct do the following test:
1. With the engine stopped, remove the oil pressure switch (see page 8-9), then install an oil pressure
gauge (A).
2. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem
before continuing.
3. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should
be:
4. If the oil pressure is out of specifications, inspect these items:
 Blocking of oil filter (see page 8-11).
 Blocking of oil screen.
 Inspect the oil pressure relief valve (see page 8-15).
 Inspect the oil pump (see page 8-17). 1. Warm up the engine.
2. Remove the drain bolt (A), and drain the engine oil.
3. Reinstall the drain bolt with a new washer (B).
4. Refill the engine with the recommended oil
(see page 3-2).
Do not overtighten.

29. Reconnect all connectors.
30. Update the ECM/PCM if it does not have the latest
software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
31. Start the engine, and let idle.
32. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the secondary HO2S (Sensor 2) and
the ECM/PCM. If the ECM/PCM was updated,
substitute a known-good ECM/PCM (see page 11-7),
then go to step 31. If the ECM/PCM was substituted,
go to step 1.
Go to step 33.
33. Monitor the OBD STATUS for DTC P0141 in the DTCs MENU with the HDS.
If the ECM/PCM was updated,
troubleshooting is complete. If the ECM/PCM was
substituted, replace the original ECM/PCM
(see page 11-228). If any other Temporary DTCs or
DTCs were indicated in step 32, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the secondary
HO2S (Sensor 2) and the ECM/PCM. If the ECM/
PCM was updated, substitute a known-good ECM/
PCM (see page 11-7), then go to step 31. If the ECM/
PCM was substituted, go to step 1. If the screen
indicates NOT COMPLETED, keep idling until a
result comes on. NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 If any of the DTCs listed below are indicated at the same time as DTC P0171 and/or P0172, troubleshoot
those DTCs first, then recheck for P0171 and/or P0172.

1. Check the fuel pressure (see page 11-325).
Go to step 2.
 If the pressure is too high, replace the fuel pressure regulator (see page 11-337), then go to
step 7.
 If the pressure is too low, check the fuel pump, the fuel feed pipe and the fuel filter. If they are
OK, replace the fuel pressure regulator (see page
11-337), then go to step 7.

for 10 minutes with the HDS.
Go to step 9.
Intermittent failure, the system is OK at this
time.
9. Turn the ignition switch to LOCK (0).
10. Check the fuel quality.
Go to step 11.
Drain the tank, fill it with a known-good fuel,
then go to step 25.
11. Inspect the spark plugs (see page 4-21). If the spark plugs are fouled or worn, replace them.
12. Test-drive the vehicle for several minutes in the range of these recorded freeze data parameters:
 ENGINE S PEED
 VSS
 REL TP SENSOR
 CLV (calculated load value)
 APP SENSOR
13. Check the CYL1 MISFIRE, CYL2 MISFIRE, CYL3 MISFIRE, and/or CYL4 MISFIRE in the DATA LIST
for 10 minutes with the HDS.
Go to step 14.
Go to step 25. 14. Check the fuel pressure (see page 11-325).
Go to step 15.
 If the fuel pressure is too high, replace the fuel pressure regulator (see page 11-337), then go to
step 25.
 If the fuel pressure is too low, check the fuel pump, the fuel feed pipe, and the fuel filter. If
they are OK, replace the fuel pressure regulator
(see page 11-337), then go to step 25.
15. 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.
16. Check for these conditions:  Engine coolant temperature (ECT SENSOR 1)above80°C(176°F)
 A/T in P or N, M/T in neutral
 All electrical loads off
17. Monitor the ENGINE SPDEED in the DATA LIST with the HDS, and hold the engine speed at
2,500 rpm. Once the engine speed is met, hold the
accelerator pedal steady for more than 10 seconds.
Repeat step 17.
Go to step 18.
18. While holding the engine speed at 2,500 rpm, check the MAF SENSOR in the DATA LIST with the HDS.
Go to step 19.
Replace the MAF sensor/IAT sensor (see page
11-224), then go to step 25.
Does the CYL1 MISFIRE, CYL2 MISFIRE, CYL3 M I SF I RE , and / or CY L4 M I SF I RE show mi sf i r ecounts?
Is the quality good?
Does the CYL1 MISFIRE, CYL2 MISFIRE, CYL3M I SF I RE , and / or CY L4 M I SF I RE show mi sf i r ecounts? Is the fuel pressure OK?
