PRECAUTION
FUEL PUMP -WALBRO ECU 1
N
NOTE
Another possible cause of the malfunctioning of the TPS/AIR TEMPERATURE/H O TEMPERATURE sensors may be the
absence of 5 Vdc power supply.
Check as follows:
Disconnect AIR TEMPERATURE/H O TEMPERATURE/TPS according to the anomaly encountered and check by turning
the board and using the volthmmeter that:
• on pin 2 of AIR TEMPERATURE connector (or on Pin 1/C5 of ECU) there is a voltage of between 4.5 ~ 5.5 Vdc
• on pin 2 of ENGINE TEMPERATURE (or on pin 1/C6 of ECU)
• on pin 1 of TPS command (or on pin 1/B5 of ECU)
