(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Data List / Coolant Temp.
(e) Read the Coolant Temp twice, when the engine is both cold and warmed up.
Standard:
With cold engine
Same as ambient air temperature.
With warm engine
Between 75锟斤拷C and 95锟斤拷C (167锟斤拷F and 203锟斤拷F).
NG -- REPLACE ENGINE COOLANT TEMPERATURE SENSOR See: Engine, Cooling and Exhaust/Cooling System/Engine -
Coolant Temperature Sensor/Switch/Engine Temperature Sensor/Service and Repair/Removal
OK -- Continue to next step.
22. INSPECT MASS AIR FLOW METER SUB-ASSEMBLY
HINT
Inspect the mass air flow meter sub-assembly See: Powertrain Management/Computers and Control Systems/Air Flow
Meter/Sensor/Testing and Inspection/On-Vehicle Inspection.
NG -- REPLACE MASS AIR FLOW METER SUB-ASSEMBLY See: Powertrain Management/Computers and Control
Systems/Air Flow Meter/Sensor/Service and Repair/Removal
OK -- Continue to next step.
23. CHECK VALVE TIMING
HINT
Check the valve timing See: P0011.
NG -- ADJUST VALVE TIMING See: Engine, Cooling and Exhaust/Engine/Service and Repair/Overhaul/Disassembly
OK -- Continue to next step.
24. CHECK SPARK PLUG
(a) Remove the ignition coil assembly and the spark plug of the misfiring cylinder.
(b) Measure the spark plug electrode gap.
Maximum gap:
1.4 mm (0.0551 in.)
(c) Check the electrode for carbon deposits.
Recommended Spark Plug
NOTICE:
If the electrode gap is larger than the maximum, replace the spark plug. Do not adjust the electrode gap.
(d) Reinstall the ignition coil assembly and the spark plug.
NG -- REPLACE SPARK PLUG See: Powertrain Management/Ignition System/Ignition Coil/Service and Repair/Removal
