Kalergie83 Posted July 13, 2024 Report Posted July 13, 2024 We have a Link programmer remotely working on our ECU. He mentions that based on the log, the Idle control valve has no function. Attached is the log. It was working fine before and this issue started suddenly. It could be a simple mechanical failure (rust). But before we take it out and check, we are wondering if it is a wiring issue. Which pin does it use, please? Thanks L37Log 2024-07-7 3;00;01 pm.llg Quote
Adamw Posted July 14, 2024 Report Posted July 14, 2024 What ecu do you have? It looks more like an issue with the speed sensor in your log to me, the idle control is locked out most of the time as the speed is showing some exaggerated value. In the areas the idle control is active it looks like the valve is having an influence. Kalergie83 1 Quote

Adamw Posted July 15, 2024 Report Posted July 15, 2024 In the idle control function, set the speed lockout to OFF to see if it behaves any different. Do a new log and attach the tune. Quote
