code P2188 help, an update
I have a 07 GXP auto tran with 86K miles. Just bought it 3 month ago. So far had flushed the coolant and did a trans fluid change. But now it has a check engine light on for the last 2 days, scan for code, shows fault code P2188. I did a search on the forum, but did not get much information. The code means leaking fuel pressure regulator or leaking fuel injector. I know the fuel pressure regulator is in the fuel tank. Two weeks ago, when i put gas in the tank, the gas nozzle did not shut off when full, so i have some gas spillage and the tank was over filled. But the car run fine, gas mileage is right on. SO i did not think twice about it( no CEL), yesterday, the tank was half full, the CEL light went on, so i filled the gas tank to full today, the light still on. Any thoughts? the car runs fine even with the CEL on, I guess is that the fuel pressure regulator is fooled because of gas over fill and when the tank is half full, it start to tell the fuel pump in the tank to send out more gas than needed. any thoughts?
I sure hate the thought of replacing the fuel injector,
Update: the CEL is off for the pass 2 days and kept off, the car still runs normal as before. thanks all for the help.
