Help Needed!!!

P 1220 & P1221. Codes will NOT clear. Car stays in reduced power mode and is undriveable. Has happend a few times in the past, but was very random. WHAT DO I DO???

[98GreenC5]

p1220 is throttle position sensor,
p1221 is throttle position sensor 1-2 correlation.

check the connector and wires the sensor(passenger
side of the throttle body) .

These codes check for the relationship between
the throttle pedal and the throttle position to
see that the throttle blade opening agrees with
the pedal.

Hope this helps.................

Thanks Dick, I'll check all that stuff today. Hope all is well.

Anyone else deal with this before?

Dick, you called it. I unplugged the sensor, cleaned it up a bit and plugged it back in. Problem seems to be solved. Thanks again!!!

Check the connection to the TPS sensor(Passenger side of TB), clean the grounds on the chassis you can see, and follow the harness from the TPS sensor back to see if there are any cuts or kinks.

Nah dude, that can't be it
