Talon FWD L4-1997cc 2.0L DOHC VIN Y SMFI (1997)
Air/Fuel Mixture: Testing and Inspection
1. Before inspection, set vehicles in the following condition:
^
Engine coolant temperature: 80 - 95° C (176 - 203° F)
^
Lights*, electric cooling fan and all accessories: OFF
^
Transaxle: Neutral (P range on vehicles with A/T)
2. After turning the ignition switch to OFF, connect the scan tool to the data link connector.
3. Start the engine and run it at 2,500 r/min for 2 minutes.
4. Set the CO, HC tester.
5. Check the CO content is 0.5% or less and the HC content is 100 ppm or less at idle.
6. If the idle speed is outside the standard value, check the following items:
^
Diagnostic output
^
Closed-loop control (When the closed-loop control is carried out normally, the output signal of the heated oxygen sensor repeats between 0 - 400
mV and 600 - 1,000 mV at idle.)
^
Fuel pressure
^
Injector
^
Ignition coil, spark plug cable, spark plug
^
EGR system and the EGR valve leak Evaporative emission control system
^
Compression pressure
NOTE: Replace the three-way catalyst whenever the CO and HC contents do not remain inside the standard value. (even though the result of the
inspection is normal on all items.)
* In vehicles for Canada, the headlight, tail light, etc. will stay on even when the lighting switch is turned OFF but this is no problem.
