Question about 2001 Oldsmobile Bravada
Have had several problems replaced o2 sensors abs sensors hub bearing assemblies and evap canister purge solenoid and keeps reading a code of small leak detected in emissons . Any ideas??? code p402 404 also the heater motor always is running maybe a short??
I have seen the rubber o ring on the gas cap leak or have dirt under it. Newer chevy pickups are know for this. causes code 402 normally. check your blower motor resistor on the heater box this can cause the fan to run all the time.
