TABLE OF FAULT CODES
CHECKS AND REMEDIES
Check thermostat
Check radiator
Check hose
Check wiring
Check the continuity (R=0 Ohm) between the trans-
ducer and ECU (blue wire – white wire - blue/yellow
wire –white/yellow wire). Check opening of the circuit
(R=infinite) between the pickup and earth
Check connectors
Check resistance (R=385 +/- 20% Ohm) between the
positive and negative poles of the pickup
Check the end screw (which shouldn't be tampered
with)
Adjust throttle cable
Check connector wires
Check connectors
Check continuity (R=0 Ohm) between the sensor and
ECU (yellow/brown wire - pink wire - white wire - yellow
wire)
Replace throttle body
Check sensor wiring
Check connectors
Check the continuity (R=0 Ohm) between the sensor
and ECU (brown/yellow wire - pink wire - white wire -
yellow wire)
Replace throttle body
Remove traces of water and try again. If necessary,
replace the butterfly casing.
