Check the power supply to the water detection sensor:
+ 12 V after relay track 1 water detection sensor
earth track 2 water detection sensor
Carry out the necessary repairs.
If none of these checks reveal any faults:
–Replace the water detection sensor (see MR 364, Mechanics, 13A, Fuel supply).
–Clear the fault.
–Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds,
to confirm the repair.
Note:
if the level of water in the fuel filter unit is lower than the sensor electrodes, certain driving conditions (on a bend,
hill) may causethe injection warning light to light up erratically.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
A drop in engine speed followed by nominal behaviour from the vehicle is possible.
Special notes:
If this fault is present:
–It is impossible to start the vehicle,
–the level 1 warning light is lit.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.

Track D1Track 2 Camshaft sensor
Injection computer brown 48-track connector B,
Track A1Track 1 Camshaft sensor
With the ignition on and the camshaft sensor connected:
Use a voltmeter to measure the voltage between tracks 1 and 3 of the camshaft sensor:
The voltage displayed should be equal to the battery voltage 0.08 V)
–If the voltage is outside permitted tolerance values, take the measurement again on the connector, with the
camshaft sensor disconnected,
–If the voltage is still outside permitted tolerance values with the sensor disconnected.
Check for continuity and absence of interference resistance on the following connection:
Camshaft sensor, track 3 Track 5 injection supply relay mounting
–If the measured voltage is correct with the sensor disconnected.
Measure the camshaft sensor resistance between tracks 2 and 3.
Replace the sensor if its resistance is not 10,250 ± 500 Ω at 20˚C
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Special notes:
If the fault is stored, clear the fault from the computer memory.
Switch off the ignition, start the engine and check that the fault does not reappear.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the engine speed sensor and camshaft sensor connectors.
Check the injection computer connections.

With the connector disconnected, check the continuity and absence of interference resistance on the following
connections:
injection computer connector B, track A1 track 1 of the camshaft sensor
