pureguava Posted December 20, 2019 Report Share Posted December 20, 2019 Hello non federal 2000 V8 GT - no EGR valves or pipes etc. swapped chips to a #1 now getting a CEL with codes p0447 p0453 p1405 p1311 Car running very well but CEL stays on. Have reset / cleared it and it returns in a few seconds - any one have advice? It seems all related to the EGR system that my car does not have - so are these faults due to just that - are the new chips looking for EGR info that is non existent? thank you for all help.

sailorbob Posted December 20, 2019 Report Share Posted December 20, 2019 Only P1405 is related to EGR, P0447 and P0453 are related to the canister purge / vent and P1311 is the rough road sensor. The service notes state these are all for USA spec. cars so I suspect your chips are for federal spec. engines. 1 Quote Link to comment Share on other sites More sharing options...
