P0207

Injector Circuit Malfunction - Cylinder 7

DTC P0207, sometimes indicated as P020700 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing injector circuit malfunction - cylinder 7.

The P0207 code means that there is a problem with the cylinder 7 injector circuit. This could be caused by a defective injector, a wiring problem, or a problem with the ECU.
If you have a scan tool, you can check the injector pulsewidths to see if they are all the same. If they are not, then it's likely that the problem is with the injector. If the injector is okay, then the problem is likely with the wiring or the ECU.

9999 CHEVROLET 2500 HD with 144000. miles

My vehicle, a 2005 Chevrolet 2500hd with a diesel, experienced engine loss of power and trouble code P0207 was stored in the pcm. This is a known problem by gm and there is a tsb #05-06-04-047c that addresses this problem. My concern is that this could happen at any time while in operation at highway or low speed. When the code is set the engine goes into limp mode and could cause an accident. Since most people that buy these to tow heavy loads a loss of power could be very dangerous in traffic. The service bulletin does extend the warranty however these vehicles are on the road long after the warranty runs out. Mine has 144,000 miles and the problem just happened. In my opinion this problem should be a recall that should be done under warranty for the life of the truck as i feel that this a safety concern.

2005 GMC SIERRA 3500 with 59921.0 miles

Driving 75mph in heavy highway traffic the check engine light came on and the truck lost power and slowed to 40 mph in about 200 yards. We almost got hit by all the traffic behind and around us as this happen without any warning. We got to the side of the hwy and i have a scanner and found 2 codes P0207 and P2146. I got out and checked the wiring to the #7 injector and did not find anything. Plugged it back in cleared codes ,engine ran fine so start down the road again. After 5 miles it did it again. It took me 5 hours to go 90 miles to get to the next city. At the hotel i found that gm has a tech bulletin for these faults and it was published in 2008 at least. So i went to a dealer and was told they would charge me for this repair. I want to know why gm did not notify me of this known defect in 2008 so i could have the truck repaired in 2008? This defect causes the truck to loose so much power that it will slow in traffic which could cause an accident. Why would this not be a recall that gm should pay for ? Gm tb number is 05-06-04-047c which tells you what happens to the truck when this defect happens.
