(p) Stop the engine. Check that the fuel pressure
remains above I.5 kg/cm2 (21 psi, 147 kPa) for 5
minutes after the engine is turned off.
If pressure is not as specified, check the fuel pump,
pressure regulator and/or injectors.
CqI After checking fuel pressure, disconnect the battery
negative (-1 cable and carefully remove the SST to
prevent gasoline from splashing.

INSPECTION OF ISC VALVE
1. INSPECT RESISTANCE OF ISC VALVE
Using an ohmmeter, measure the resistance between ter-
minal B~l - Sl or S3 and 82 - S2 or S4.
Resistance: Bl -SlorS3 PO-3051
B2-S2orS4, lo-30n
If resistance is not as specified, replace the ISC valve.
2. INSPECT OPERATION OF ISC VALVE
(a) Apply battery voltage to terminals Bl and 82 and
while repeatedly grounding Sl - S2 - 53 - S4 -
S 1 in sequence,.. check that the valve moves toward
the closed position.
(b) Apply battery voltage to terminals Bl and 82 and
while repeatedly grounding S4 - S3 - S2 - Sl -
S4 in sequence, check that the valve moves toward
the open position.
INSPECTION OF CHECK VALVE (7M-GTE only)
INSPECT CHECK VALVE
Inspect the check valve for damage and the diaphragm for
cracks.
If necessary, replace the check valve.
INSTALLATION OF ISC VALVE
1. INSTAiL ISC VALVE
(a) (TM-GTE)
