After returning from a two-week vacation (not driving my car), my "Service Engine Soon" light came on. Autozone printed me out a paper that said:

Troubleshooting P1126

Definition
Throttle control motor relay open
Probable Causes
1-Open or short circuit condition
2-Throttle control motor relay circuit open
3-Failed relay

I have not noticed any symptoms of problems. My car continues to run well. However, I imagine these lights come on for a reason and I would rather get it fixed early.

Do I just need to clean a sensor or make a small fix? or should I take it to a shop and have it looked at?

Suggestions?

Possible causes:
- the thermostat could be bad
- there's a leak in the seal
- the thermostat could be stuck open
- the coolant temp sensor is bad
I got the same code on a 2000 Sentra and the Advance Autoparts says Fuel Air Metering So I pulled the MAF for nothing.
