ozzy Posted June 15, 2022 Report Share Posted June 15, 2022 I cant seem to get idle control valve working. Its not a stepper motor. Its a solenoid valve. Reading through all the topics nothing seems to work. I think my car originally had stepper motor. Checking the pinout it says b137-1 open end b137-2 close end. "The set up will be vary similar to the 2 wire control but with only one channels needed. Just pick an Aux and then assign as ISC Solenoid. Check the frequency settings etc and make sure the second drive is now turned off. " Can you check the map. I dont know how to check frequency settings to "make sure the second drive is now turned off" Thanks e22_acun_son.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 16, 2022 Report Share Posted June 16, 2022 A V4 originally had a 3 wire valve - the valve is supplied 12V to the middle pin from the chassis wiring, the ecu grounds one end to open the valve or grounds the opposite end to close. Only the V5&6 had a stepper motor. Then in V7 they changed to a different type of 3 wire valve that only needed a single control wire, not a push pull type like V1-4. So provided you do have a normal V4 idle valve then Aux 1 should be set to "ISC Sol. Slave" and Aux 2 should be set to "ISC Solenoid" and 200Hz. The rest of your settings look ok.

ozzy Posted June 16, 2022 Author Report Share Posted June 16, 2022 I have the new type idle control solenoid v7. Sorry I forgot the most important part. This is my problem. Unfortunately couldn't find the old valve. How can I get this new one working. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 16, 2022 Report Share Posted June 16, 2022 Looks like Pin 1 goes to an aux on the ecu - you can use either aux 1 or 2. You can use one of the aux wires that is already there. Pin 2 is +12V, you can use the 12V wire that is already there. Pin 3 is Ground, you can probably just connect this to the engine block or other good ground point. Do you have it wired like this?

ozzy Posted June 16, 2022 Author Report Share Posted June 16, 2022 I have it wired exactly like this. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 16, 2022 Report Share Posted June 16, 2022 So did you wire it to aux 1 or 2? if you set whichever aux you have used to "test PWM" at 10Hz does it click? You know the connector pic above is looking back into the plug on the loom - wires pointing away from you? Quote Link to comment Share on other sites More sharing options...
ozzy Posted June 16, 2022 Author Report Share Posted June 16, 2022 I wired it to aux 1. I will check whether i did wire the connector as you described. I will check and get back you you. Since i only have one wire going to ecu i assume my settings are fine for v7 right? or shall i change it to the way you described (aux 1 ISC Sol. Slave. aux 2 isc sol).(this seems wrong to me for v7) Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 16, 2022 Report Share Posted June 16, 2022 No your original set up would have been ok for the V7 valve Quote Link to comment Share on other sites More sharing options...
ozzy Posted June 18, 2022 Author Report Share Posted June 18, 2022 Ok now it's working perfectly. Thanks so much Quote Link to comment Share on other sites More sharing options...
