1996 Cadillac Deville V8 Front Wheel Drive Automatic 200, 00 miles
The car was being driven down the highway and suddenly lost acceleration. If you pushed the accelerator it was like revving it in neutral. All gears are now like neutral. Soon as that happened we got the 'Service Transmission' message. We ran the diagnostic check and have 3 codes:
P1139 - Heated Oxygen Sensor
P0301 - Cylinder 1 misfire
P1810 - TFP Valve Position Switch Circuit
What exactly does the last code mean (P1810)? Does this mean it is an electrical problem? A faulty valve? Any ideas or suggestions?
I appreciate any help or advise you can supply!
Thanks so much ~
