Code P014, Shorted ECT Sensor Signal: Action
1992 Saturn SL1 AutomaticSECTION Action
WARNING: This page is about a different car, the 1995 Cadillac Seville. However, it is still accessible from the selected car via links, so may be relevant.
PCM turns on MIL and uses IAT sensor value instead of coolant sensor value for all calculations during first 10 minutes of operation; it then uses a value of 194°F (90°C). Transaxle shift adapts are maintained at current levels.
NOTE:
Test numbers refer to numbers on diagnostic chart.
- With ECT sensor or wiring shorted, PCM parameter PD04 should indicate 148°C or greater. If PD04 does not indicate 148°C or greater, sensor or wiring is not shorted.
- Checks for shorted sensor or circuit No. 410. If parameter value stays at 147°C or greater with sensor unplugged, short is in circuit No. 410 between terminal "B" and PCM terminal 1B5.
- Check PCM connector. Fault is most likely at PCM connector or PCM.
