This is a strange issue, as it only lights up the check engine light a few days a month. And from the sounds of things, no a huge issue.

HI there,

The code is for the throttle position sensor. Sometimes cleaning the electrical connector and using di electric grease will solve the issue. If not, then the whole throttle body must be replaced. The engine may run strange for a short time after you unplug the TPS as the electronic throttle re calibrates it's parameters.
