The crd kind of missed a few beats or loss of power, Check engine light came on and the went off. Now I have three codes P0139/ P0299 and P0625 but it still runs fine. Can some one decode these codes for me

How do you people see these codes?

I found 2 of the codes, but couldn't find PO299.
P0139 HO2S Slow Response Bank 1 Sensor 2
P0625 Generator F-Terminal Circuit Low Voltage

They can be read on the odometer by following the instructions on the link below:

Normally, to get codes, you put the key on OFF and then rapidly do OFF-ON-OFF-ON-OFF-ON (on some cars you have to do four or five, not three, OFF-ON cycles). On our test 2002 car, the key did not go back to unlock, so it was ACC-ON-ACC-ON-ACC-ON.

thanks for the info. On my old GMC I use a jumper wire to jump two terminals on the computer plug-in and it causes sequences of the service engine light to flash.

Well I took it to the dealer and they found a leak (drip-drip not squirt) where the common rail screws into the #4 injector. They are supposed to have the new metal fuel line in on Friday. The tech thinks the rail pressure sensor picked the leak and sent the codes.
