My brother is on the road and has gotten this code under acceleration. Anybody seen this or heard of this before. He's checking his harness connections.

Was just hoping for some more info.

P0205 injector #5 control circuit???

Hope this helps,
Disconnect the pigtail nuts from the suspect injector. Using an Ohmmeter, measure the resistance between the solenoid posts of the injector.
NOTE: Be sure to zero the ohm meter prior to checking the injector circuit.
Is the resistance less than 1 ohm and greater than 0 ohms?
No
Replace the fuel injector

Brilliant forgot to tighten #5 injector nuts when doing head studs!! [laugh]

thats always good. I've dont stuff like that too!
