Help with code

[gman1113]

Can anyone tell me what the code P1117 is?

Any help appreciated

Thanks

You never said what year and model, which is ALWAYS critical for code definitions.

Depending upon the above, it may be the O2 sensor heater on bank #1 ahead of the main cat.

OK, P1117 is the code for a heater failure on the O2 sensor ahead of the cat on bank #1. Diagnostics are to check the heat circuit on that sensor for resistance (should be 1.8- 2.5 ohm), a short to ground, or no voltage. If everything is OK, replace the sensor.
