INSPECTION PROCEDURE
HINT:
• If diagnostic trouble code "22" (engine coolant temperature sensor circuit), "24" (intake air temperature sensor circuit) and "41" (throttle position sensor circuit) are output simultaneously, E2 (sensor ground) may be open.
1 Check voltage between VTA1, IDL1 and E2 of engine control module connector.
P (1) Connect SST (check harness "A").
(See page EG-404)
SST 09990-01000
(2) Turn ignition switch ON.
(3) Disconnect the vacuum hose from the throttle body, then apply vacuum to the throttle opener.
(See page EG-219)
C Measure voltage between terminals VTA1, IDL1 and E2 of engine control module connector when the throttle valve is opened gradually from the closed condition.
OK
Terminal VTA1 - E2 IDL1 - E2
Throttle Valve
Fully Closed 0.3 - 0.8 V 0 - 3.0 V
Fully Open 3.2 - 4.9 V 9 - 14 V
Hint The voltage should increase steadily in proportion to the throttle valve opening angle.
