Check :

maximal pressure

- Sealing between manifold and transducer.

- Valves clearance.
- Canister purging valve operation
- Cylinders compression
- Lack of leaking at inlet manifold (“false air”)
- Exhaust is not clogged.

If all these elements are correct, replace the transducer.

WATER TEMPERATURE

RECOMMENDATIONS

No failure must be present or memorized.

If the value red is incoherent, check that sensor is correctly following the standard curve “resistance
subject to temperature”.
Replace the sensor if this is presenting deviations (Observation: the presence of the deviations from
normal values of a sensor are often due further to an electric shock).

Check the insulation, continuity and the absence of the parasite resistance of the connections
between:
Pin 13 injection computer > pin B2 water temperature sensor
Pin 73 injection computer > pin B1 water temperature sensor
Mend if necessary.

AIR TEMPERATURE

RECOMMENDATIONS

No failure must be present or memorized.

If the value red is incoherent, check that sensor is correctly following the standard curve
“resistance subject to temperature”.
Replace the sensor if this is presenting deviations (Observation: the presence of the deviations
from normal values of a sensor are often due further to an electric shock).

Check the insulation, continuity and the absence of the parasite resistance of the connections
between:
Pin 49 injection computer > pin 1 air temperature sensor
Pin 77 injection computer >

pin 2 air temperature sensor.
