NO.14 POOR FUEL ECONOMYA6E398018881203
Diagnostic procedure
14 POOR FUEL ECONOMY
DESCRIPTIONFuel economy is unsatisfactory.
POSSIBLE CAUSE•Contaminated air cleaner element
•VIS malfunction (if equipped)
•Engine cooling system malfunction
•Improper ATF level (ATX)
•Weak spark
•Poor fuel quality
•Erratic or no signal from CMP sensor
•Clutch slippage (MTX)
•VTCS malfunction
•Improper variable valve timing control system operation (if equipped)
•Improper coolant level
•Inadequate fuel pressure
•Spark plug malfunction
•PCV valve malfunction
•Brake dragging
•Improper valve timing due to jumping out of timing belt
•Contaminated MAF sensor
•Improper engine compression
•Exhaust system clogging
•Improper electrically controlled 4WD system operation
Warning
The following troubleshooting flow chart contains fuel system diagnosis and repair
procedures. Read following warnings before performing fuel system services:
•Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always
keep sparks and flames away from fuel.
•Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or
death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete
“BEFORE REPAIR PROCEDURE” and “AFTER REPAIR PROCEDURE” described in this
manual.
Caution
•Disconnecting/connecting quick release connector without cleaning it may possibly cause
damage to fuel pipe and quick release connector. Always clean quick release connector
joint area before disconnecting/connecting, and make sure that it is free of foreign material.
STEP INSPECTION RESULTS ACTION
1 Inspect for following:
•Air cleaner element for contamination
•ATF level
•Fuel quality
•Coolant level
•Brake dragging
•Clutch slippage
Are all items okay?Yes Go to next step.
No Service as necessary.
Repeat Step 1.
2 Connect WDS or equivalent to DLC-2.
Retrieve any continuous memory, KOEO and
KOER DTCs.
Are there any DTCs displayed?YesDTC is displayed:
Go to appropriate DTC test.
NoNo DTC is displayed:
Go to next step.
3 Access ECT PID.
Drive vehicle while monitoring PID.
(See F1–33 PCM INSPECTION (4WD).)
Is PID within specification?Yes Go to next step.
No Inspect for coolant leakage, cooling fan and condenser
fan operations or thermostat operation.

4 Is strong blue spark visible at each disconnected
high-tension lead while cranking engine?Yes Inspect for following:
•Spark plugs malfunction
•CMP sensor is improperly installed.
•Trigger wheel damage on camshaft
•Open or short circuit on CMP sensor
•Open or short circuit between CMP sensor and
PCM terminal 2J or 2M
Repair or replace malfunctioning parts.
If okay, go to next step.
No Inspect following:
•High-tension leads
•Ignition coil and connector
5 Install fuel pressure gauge between fuel pipe
and fuel distributor.
Start engine and run it at idle.
Measure fuel line pressure at idle.
Is fuel line pressure correct at idle?Yes Go to next step.
NoZero or low:
Inspect for clogged fuel line.
If okay, replace fuel pump unit
High:
Replace fuel pump unit.
6 Inspect for VTCS operation.
Does VTCS work properly?Yes Go to next step.
No Repair or replace malfunctioning parts.
7Note
•The following test should be performed for
vehicles with variable valve timing control
system. Go to next step for vehicles
without variable valve timing control
system.
Inspect for variable valve timing control system
operation.
Does variable valve timing control system work
properly?Yes Go to next step.
No Repair or replace malfunctioning parts.
8Note
•The following test should be performed for
vehicles with VIS. Go to next step for
vehicles without VIS.
Inspect for VIS operation.
Does VIS work properly?Yes Go to next step.
No Repair or replace malfunctioning parts.
9 Remove and shake PCV valve.
Does PCV valve rattle?Yes Go to next step.
No Replace PCV valve.
10 Inspect for restriction in the exhaust system.
Is there any restriction?Yes Inspect exhaust system.
No Go to next step.
11 Inspect for contaminated MAF sensor.
Is there any contamination?Yes Go to next step.
No Inspect for cause.
12 Inspect MAF sensor for contamination.
Is there any contamination?Yes Replace MAF sensor.
No Go to Step 14. (2WD)
Go to next step. (4WD)
13 Inspect electrically controlled 4WD system
operation.
Is operation of electrically controlled 4WD
system okay?Yes Go to next step.
No Repair or replace malfunctioning parts.
14 Is engine compression correct? Yes Inspect valve timing.
No Inspect for cause.
15 Verify test results.
•If okay, return to diagnostic index to service any additional symptoms.
•If malfunction remains, replace PCM. STEP INSPECTION RESULTS ACTION
