Daytona IROC V6-181 3.0L SOHC VIN 3 FI (1992)
-
Injector pulse width, (switching the ground on and off twice per engine revolution).
-
Idle speed, through the IAC motor.
-
Ignition timing.
Note: The PCM enters "Closed Loop" operation after the engine reaches operating temperature and the delay has elapsed.
Wide Open Throttle (WOT)
PCM MONITORS:
-
Engine Temperature (ECT)
-
Manifold Vacuum (MAP sensor)
-
Engine rpm (distributor pick-up)
-
Throttle Opening (TPS)
-
Battery Voltage
PCM CONTROLS:
-
De-energizes EGR system, by grounding Electronic EGR Transducer (EET) solenoid.
-
Adjusts injector pulse width, to supply additional fuel.
-
Monitor oxygen sensor and fine tune air/fuel ratio by varying injector pulse width
-
Adjust ignition timing.
-
De-energize A/C Compressor Clutch relay (if selected)
Ignition Switch Off
When the ignition switch is OFF the PCM interrupts the ground to the ASD and fuel pump relays.
Warm Idle
PCM MONITORS:
