Hi,

We urgently need information for a reputable Cadillac repair shop in the Plano or Northern Dallas area in TX. We drove our car from California to Texas with the Service Engine Soon light on with no problem at all. We had all 4 oxygen sensors replaced before we left and they all came back the next day with the same errors.

P0135 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 1
P0141 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 2
P0147 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 3
P0155 - Heated Oxygen SenPCM sor (HO2S) Heater Performance Bank 2 Sensor 1


When you run a scanner, the codes will clear but they come back again the next day.

Now we need to register the car in Texas and we will not pass the State inspection if we don't have the service engine light removed.

Your speedy reply will be most appreciated.

Thanks,

Eldo

Oooops, forgot to mention this is for a 1997 Cadillac Eldorado ETC.

Try Bass Automotive in Richardson. I have personally never tried them but I have heard good things about them and they are familar with Caddy's.

Thank you very much for the reply, DiamondEldo. We will try them out.
