RESISTANCE OF THE RPM TIMING SENSOR: (AT 25°C)
Specification Desc./Quantity
1 Model with 1 clamp: 860 Ω ± 130 Ω
2 Model with 2 clamps: 680 Ω ± 100 Ω
YES go to 11 NO go to 12
11 - Check the earth isolation between a pole and the shielding.
(see the «Electrical system» chapter).
Electric characteristic
S - + =
infinite (>MΩ)
YES go to 13 NO go to 12
12 - Replace the revolution sensor.
13 - Reconnect the rpm-timing sensor connector.
Repeat the resistance check through the injection
wiring pin 7, pin 12.
Electric characteristic
7-12 =
680 Ω ± 100 Ω (Model with 2 clamps)
7-12 =
890 Ω ± 130 Ω (Model with 1 clamp)
The value should be very close to that detected directly by the sensor.
YES go to 17 NO go to 14
14 - Higher or infinite resistance.
YES go to 15 NO go to 16
