2017年10月31日 · I appreciate the info, that is the “wire chafing” that everyone has been talking about, after a visual inspection of the wiring, I went to the injectors wiring (valve cover plug) and ohm the injectors and found the problem (#2 injector .632 ohms) now Iam pulling the valve cover to probe the injector coil itself to rule out the valve cover harness to the injector.

2018年6月27日 · A P020x code by itself (which also triggers a P2149 or P2146, that shuts down a bank of injectors to get your attention) would indicate, most likely, a loose connector to the injector. P0202 and P0207 are the notorious ones, but it can happen on any of them. But getting a bunch at the same time points more to a wiring issue in the harness.

2009年12月5日 · P0202: Number #2 injector Drive fault, incorrect current on a fuel injector circuit (the condition exists for less than 1 second)... you should have freeze frame data with this one (operating conditions). The control module will disable the fuel injector with the concern. that'll be why it's running so rough. 2149 is a sister code set with it.

2014年4月1日 · P0202 (injector circuit, open cylinder #2) P2149 (fuel injection group B supply, injection circuit open) after messing with some wires truck started, and ran ok so I cleared the codes. Last night I was looking it over and found a wire rubbed through the insulation @ the alternator bracket. Yahoo! I taper her up figured problem o fixed!

2010年1月6日 · I had a great ride in my 01 duramax until jan 09, 95000 miles. Engine loses power, starts to clatter, shows codes, p0202, p0203, p0205, p0208, p1262. shows check engine light, fuel ga. goes to empty and low fuel light comes on. Sometime it will return to normal by shutting off for a min, and restarting. Problem will return some time soon.

2010年2月24日 · Here we go again. January 2005 had P0202 (Injector Circuit Malfunction-Cylinder 2, also P2149 (FICM (fuel injection control module)...New engine wiring harness installed under warranty (32,000 miles)...Doc ID# 1566267. Today, it is de javu all over again, though MORE THAN 5 years later, 98,000 miles, same doggone P0202 & P2149 codes.

2010年1月1日 · P0202 (injector circuit, open cylinder #2) P2149 (fuel injection group B supply, injection circuit open) I am now at a standstill and do not know what to do from this point on. I have a good mechanical background, but I am not going to claim to …

2022年2月22日 · 10. After work I test fired the truck 10x to establish a benchmark. P0202, P0203, P0205, and P0208 would show in random groups of any 1, 2, or 3 of these codes, as well as all 4, in each case accompanied by P2149. Changed the fuel filter (embarrassed to admit it was at 30K miles...life gets busy sometimes), pumped the primer pump, and VOILA, no ...

2017年2月8日 · If the vehicle had only injector circuit codes for P0202 or P0207 (with bank shutdown P2146 or P2149), and the wiggle test induces a P0202 or P0207 to reset, use bulletin number 05-06-04-047B to repair the injector connectors and …

2021年4月1日 · LLY started knocking very bad and went into limp mode. The truck is not blowing any smoke. I scanned the truck and got P0202, P0203, P0205, P0208, P2149. I attempted to wiggle injector harness 2 and 7 with no change in how it was running. Any input on what it could be? Should I start by replacing injector 2 and 7s harness?
