Monitors for Engine Misfire At: |
|
| Non-LDP |
4 X 1000 RPM Counter (4000 Revs) (Type B) |
|
| LDP |
**200 X 3 (600) RPM counter (Type A) |
|
| Requires 3 Consecutive Global Good Trips to Extinguish the MIL* |
Requires 3 Consecutive Global Good Trips to Extinguish the MIL* |
Requires 3 Consecutive Global Good Trips to Extinguish the MIL |
| *40 Warm Up Cycles are required to erase DTCs after the MIL has been extinguished |
** Type A misfire is a one trip failure on pre-1999, 2 trip failure on 1999 and later. The MIL will illuminate at the first or second failure, based
on MY. |
