New S300, code 14

Post by spoonek »

Hello, I just purchased an s300 on a P28 ecu from a Hondata dealer and when first starting the car I get a code 14. I've never had that code before. The 2 wire IACV blu/ blk wire goes to the A12 plug at the ecu. I have an obd2a to obd1 jumper harness. The engine harness is a 96 EX harness with Vtec, never been cut/ modified. The Engine is a B18c5 with B18c5 intake manifold and Iacv (2 - wire). When using the P73 ecu, I don't get the code 14. Do I need to move a pin at the OBD1? Not sure why the S300 is not getting the signal. What would it hurt if I disable IACV in SManager? Thanks!

Turned out the jumper harness had a bent pin. All good now.
