Step 2
1) Turn the ignition switch OFF.
2) Disconnect the STVA coupler and remove the throttle body.
(#Page 51)
3) Check the continuity between each terminal and ground.
$ STVA continuity: ∞ Ω (Infinity)
4) If OK, then measure the STVA resistance (between terminal
A and terminal B) and (between terminal C and terminal D).
$ STVA resistance: Approx. 7 Ω

) Tester knob indication: Resistance (Ω)
Is the resistance OK?
• B/Lg, P/W, G and W/B wire open or shorted to
ground, or poor Y, [, d and f connection.
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
YES
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
• Loose or poor contacts on the ECM coupler.
NO
• Replace the STVA with a new one.
