P1519 - Idle Air Control Valve Circuit Malfunction

Post by playasyougo »

I found the issue. Pin A12 showed no continuity to ground so i've just connected it to a chassis ground along with the pin on the IACV. There maybe an issue with the ECU or a split in the wire but is grounding the connections ok to go in the opinions of the experts at Hondata? I will be more thorough when the dash is out and look for a break in the wire.

I've not managed to run the car yet as the battery was flat and it started to rain outside where the car is.

Step by step Honda procedure for checking this error code i used is here:

Managed to source the issue which is still under investigation. The gasket that was supplied with the aftermarket throttle body never fitted correctly from new and eventually gave way to extra air being sucked into the engine after sensors.
