Test
1 - Check the integrity of the terminal
and the cable:
- ECM pin 1/B2
- ECM pin1/E4
2 - Check the resistance value:
- ECM pin 1/B2 to ECM pin 1/E4
(depending on the temperature, -
see below)
3 - Check the continuity of the cable:
- ECM pin 1/B2 to sensor pin 2
- ECM pin 1/E4 to sensor pin 1
4 - Check the cabling for short
circuiting:
- pin 1/B2 al ECM pin 1/E4
5 - Check the resistance of the sensor:
- Sensor pin 1 to sensor pin 2
(depending on the temperature, -
see below)
6 - Check the cable for short circuiting:
- ECM pin 1/B2 to the chassis
7 - Reconnect the cabling, cancel the
fault code and activate the engine
to check the elimination of the fault
