Grand Caravan FWD V6-3.8L VIN L (2001)
When the PCM senses a wide-open-throttle condition through the Throttle Position Sensor (TPS) it deenergizes the A/C compressor clutch relay.
This disables the air conditioning system.
The PCM does not monitor the heated oxygen sensor inputs during wide-open-throttle operation except for downstream heated oxygen sensor and
both shorted diagnostics. The PCM adjusts injector pulse width to supply a predetermined amount of additional fuel.
Ignition Switch OFF Mode
When the operator turns the ignition switch to the OFF position, the following occurs:
-
All outputs are turned OFF, unless O2 Heater Monitor test is being run. Refer to the Emission for On-Board Diagnostics.
-
No inputs are monitored except for the heated oxygen sensors. The PCM monitors the heating elements in the oxygen sensors and then shuts
down.
