I'm getting po700 (general transmission probs), p0837 and p0839 codes - 4 wd high voltage swith codes. also part time dash message is mostly on (sometimes intermittent - on/ off) I thought I saw a post elsewhere indicating I can change out a switch... can't…
My Code reader indicates the following:
P1267 Cylinder #7 high to low short side
P1265 Cylinder #5 high to low short side
P1261 Cylinder #1 high to low short side
This is on my 2005 Jeep Liberty CRD turbo diesel with only 4 cylinders. Could this be a fuel injector issue? or maybe glow plug issue? Thanks!
Cylinder High to Low Short Side
Check valve cover wire harness connections first, including under the valve cover.
– Faulty Fuel Injector Interface Module
– Fuel Injector harness is open or shorted
– Fuel Injector circuit poor electrical connection
A fault is detected by the fuel injector interface module in the secondary (rearward) fuel injector circuit.
