DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
ENGINE (DIAGNOSTICS)
Step
I CHECK FUEL TANK CORD.
Measure the resistance between fuel sub level
sensor and coupling connector.
Connector & terminal
(R57) NO. 3
-
(R59) NO. 1:
CHECK FUEL LEVEL SENSOR.
During work procedures, if fuel tank is more
than 3/4 full, be careful because fuel may
spill.
1)Remove the fuel pump assembly. <Ref. to
FU(S0HC)-59, Fuel Pump.>
2)While moving the fuel level sensor float up
and down, measure resistance between fuel
level sensor terminals.
