Jeep TJ ForumThird generation of the classic Jeep - manufactured since 1997. Known by the coil springs and round headlights. Includes the Rubicon and Unlimited editions as well
Hi all. My 2004 Tj with 4L I6 is throwing injector open circuit codes. I don’t think I have a bad injector as the connectors are flaky and brittle and half tie wrapped together. I wanted to just get a new harness but I think the injectors must be aftermarket because there is a plug adaptor. Does anyone recognize the adaptor, injector or have experience with this to help me find the right parts? I’d rather not change all the injectors if I don’t have to

You most likely don’t need new injectors. The “injector open circuit” codes are probably caused by brittle connectors or a failing harness, especially with the plug adaptors. Replace or repair the injector harness and ensure proper wiring continuity before swapping injectors.
