Took my car in today for the same code. This is the second time. They put it on the computer for a fee, and Code P0140 came up and the report says for "Injection System Relay Circiut". They reset the code. It passed all tests and of course they weren't able to bring back on the Check engine light!

So I was told if it happened again to bring it back, and they would change out ??? and credit back my $120.00 towards my deductable. Thank goodness I bought the extended warranty.

And it seems for some reason, I'm getting about 40 miles less to a tank right now. Not sure why.

I will keep you posted, if I take it back in soon.
