Buying 2002 c5 p1221 and p0101 codes and reduce engine power?
- Thread starter C5hifive
- Start date
The first one: P0101 indicated a mass air flow meter problem.
the second one: P1221 doesn't show on the list. Might you have miscounted the flashes showing the code?
...Here's a list of all the codes:

Looks like the 1221 could be the left front wheel speed sensor circuit.

The way I look at it when buying a car is that it had better appear darned near perfect. You will find enough problems after buying never mind buying it already having problems. You can over look a few things if it is an exceptional deal.
P1221 comes up as a Throttle Position sensor from my source 
Much better than an fault with the active handling system, although parts are still available for the '02 if something like that should go whereas the '99-'00 cars are left hanging in the wind (Steering wheel position sensor)......ask me how I know....
Best way to fix these codes are with a little R&R and then clear the codes. If the car has an aftermarket air filter, it may just have oil on it from when the owner last cleaned the filter, so the MAF may just need a cleaning. This a a very common problem from people over oiling their filters.
Anyway, welcome to the forum!!!! Let us know if you find much else for sale or if you decide to go with this one!

Well, I can't upload it as the file size is too big. PM me your email address and I will send it out to anyone that wants a copy.
