Have Toyota Questions? Ask a Mechanic for Answers ASAP
hi my name is ***** ***** I can help you. the SCV gets it's signal from the ECU but before you condemn the ECU check the connectors and wire resistance from ECU to scv. also for continuity. may have broken wire. Is there any trouble lite on? hope this helps. let me know
if you can give me your "E" mail I can forward the schematics for that and you have to do all checks from the wire side as not to damage the delicate ECU connectors it should be a low voltage going to the SCV
unfortunately there is no ECU check itself that's why you have to be careful to check all perimeters around it I will dig up the diagram and send it off to you best of luck. your "E" mail address didn't come through , I have the diagram for you just waiting for e mail address. .
