Fuel Pump Control Circuit
CIRCUIT DESCRIPTION
The fuel pump is switched on (low voltage at terminal FC) when STA is on or while the NE signal is input to
the ECM.
In the diagram below, when the engine is cranked, current flows from terminal ST of the ignition switch to
the starter relay coil, the starter relay switches on and current flows to coil L1 of the circuit opening relay.
Thus the circuit opening relay switches on, power is supplied to the fuel pump and the fuel pump operates.
When the STA signal and NE signal are input to the ECM, Tr is turned ON, current flows to coil L2 of the circuit
opening relay, the relay switches on and the fuel pump operates.
While the NE signal is generated (engine running), the ECM keeps Tr ON (circuit opening relay ON) and the
fuel pump also keeps operating.

INSPECTION PROCEDURE
1 Check ATF Temperature Sensor.
PREPARATION:
Remove the ATF temperature sensor.
CHECK:
Measure resistance between terminals of ATF temperature
sensor at 20°C (68°F) and 110°C (230°F).
OK:
Resistance:
20°C (68°F): Approx. 13.0 kΩ
11 0°C (230°F): Approx. 800 Ω
NG Replace ATF temperature sensor.
OK
2 Check harness and connector between ATF temperature sensor and ECM
(See page IN−26).
NG Repair or replace harness or connector.
OK
Check and replace ECM.
