Symptom: Improper tachometer indication. OK >> Perform ECM self-diagnosis. Refer to
EC-604, " CONSULT-III Function (ENGINE) " with (MR
TYPE 1), EC-1116, " CONSULT-III Function (ENGINE) " (MR TYPE 2) or
EC-103, " CONSULT-III

Fuel Level Sensor Signal Inspection INFOID:0000000004307010
Symptom:
• Improper fuel gauge indication.
• Low-fuel warning lamp indication is irregular.
NOTE:
The following symptoms do not indicate a malfunction.
• Depending on vehicle position or driving circumstance, the fuel level in the tank shifts and the indication may
fluctuate.
• If the vehicle is fueled with the ignition switch ON, the indication will update slowly.
• If the vehicle is tilted when the ignition switch is turned ON, fuel in the tank may flow to one direction result-
ing in a change of reading.
