COOLANT TEMPERATURE
XR25 aid: # 02 = Engine temperature ± 5 °C
No fault bargraphs should be illuminated.NOTES
If the value read is incoherent, check the sensor is correctly following the standard table of values for
"resistance as a function of temperature".
Replace the sensor if the values are incorrect (
NOTE : If a sensor is incorrect, this is often due to an electric
shock).

Check the hygiene and presence of earth on track C2 of the fuel pump.
If + 12 V is not reaching the fuel pump, replace the fuel pump relay.
If + 12 V is reaching the fuel pump, replace the fuel pump.
Check the impact sensor is correctly clipped in.

The pinking sensor should give a signal which is variable and not zero, to prove that it is recording the
mechanical vibrations of the engine.
If the signal is zero:
- Check the sensor is correctly screwed in.
- Check the insulation and continuity of the wiring:
Computer 8 2 Pinking sensor
Computer 44 1 Pinking sensor
Computer 2 Pinking sensor screening
If necessary, replace the sensor.

speed
# 16 not coherent
If all these points are correct, replace the sensor.
A vacuum pump with a pressure gauge may be used to check coherence with
# 01 and to show a faulty sensor.
# 01 > Maximum at idle
speedThe manifold pressure is often a sign of incorrect engine operation. Check
- the sealing of the pipe between the manifold and the sensor,
- the valve clearances,
- the canister bleed valve which should be closed at idle speed,
- cylinder compression using the OPTIMA 5800 station.
If all these points are correct, replace the sensor.
A vacuum pump with a pressure gauge may be used to check coherence with
# 01 and to show a faulty sensor.

RICHNESS REGULATION
XR25 aid:Richness regulation faulty
No fault bargraphs should be illuminated.
Ignition correct (a check may be made using the OPTIMA 5800 station).
No other status bargraph should show a fault.
NOTES
Check the sealing of the canister bleed valve (a leak can disrupt the richness considerably).
Check the sealing of the exhaust pipe upstream from the oxygen sensor.
Check the sealing of the inlet manifold.
If the vehicle has only been driven in town, the sensor is contaminated (try driving under load).
Check the fuel pressure.
If the idle speed is unstable, check the valve clearances.
Check the injectors (flow and shape of the jet).
If necessary, replace the oxygen sensor.
Check the connection and condition of the oxygen sensor connector.
Ignition on, during the timed phase, check for:
- earth on track B of the oxygen sensor.
-+ 12 V after the fuel pump relay on track A of the oxygen sensor.
Repair if necessary.

if the value read is incoherent:
- Check that the sensor is correctly mounted and supplied:
•+12 V on A1
• Earth on B2
- Check the insulation, continuity and that there is no interference resistance on the line:
Computer 12 B1 vehicle speed sensor
NOTE : Check the different functions that use this information.
