No joy. V70-XC70 2004

Reseated the ECM and the car ran fine. When I checked for codes there weren't any. Seemed odd but maybe unplugging the ECM will do that.

Mary drove it and called to say the check engine light came on. It was still running so I did not think that it was fatal. But it goes to reduced power and ends up coming home on a flatbed.

Check engine light is off. No messages in the DIM window. It does have the P2135 and P0221 codes stored again. I didn't think the CEL would go off without multiple cycles without a fault.

Any ideas on how to ohm out the pedal sensor or thoughts about what else might be wrong ?

Thanks

Greg
