Hello I have a 2004 JTS. This afternoon I changed the oil and replaced the Air Filter, not the easiest air filter to change. On starting the engin I got 'Motor Control systen Failure Go To Dealer'. Every thing OK before I did the changes. I have an ELM327 interface and ProScsn Software which showed the following fault codes - P0481 Powertrain cooling Fan Relay 2 Control Circuit - P0480 Powertrain cooling Fan Relay 1 Control Circuit and P0135 H02S Heater Performance Bank 1 Sensor 1. I Have tried to delete them but I keep getting the same mesages. I have obviously disturb the wiring in some way when removing the top of the Air filter. Has any one any ideas please. Not road tested yet will try tomorrow.

Tank you
