P1457 EVAP System CEL Question

Post by 640k »

Are there plans to fix the EVAP System CEL (90-2 P1457 error) or is the only solution to disable ODBII?

Thanks.

The solution is to disable OBD2.

The reason an 05-06 RSX gets this code when using a K-Pro is that the 02-04 ECU controls the valve on the canister...the 05-06 does not have this control, so the 02-04 ecu is looking for something that just isnt' there in the newer cars, the only thing to do is disable OBD2 which eliminates the error. Nothing is really lost, it's just that the got more features than the car has.
