Engine Warm Up
1995 Chrysler New Yorker V6-3.5L VIN FSECTION Engine Warm Up
This is an OPEN LOOP mode.
During engine warm-up, the PCM receives input from:
- Battery voltage
- Crankshaft position (CKP) sensor
- Engine coolant temperature (ECT) sensor
- Intake air temperature (IAT) sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position (CMP) sensor
- A/C select switch
Based on these inputs the PCM will:
- Apply voltage to the injectors. The PCM then controls injection sequence and pulse width by switching individual injector ground paths on and off.
- Adjust engine idle speed through the IAC motor.
- Adjust ignition timing.
- Begin to monitor oxygen sensor. When engine is at operating temperature, the system will leave warm up mode and go into closed loop operation.
