[QUOTE="rudymags, post: 438601, member: 20868"] I have been getting a 54 code on my ‘95, 2.5L, 5 speed, 188k mileage. The CEL does not come until after I’ve driven about 5-10 minutes. I replaced the O2 sensor about 2-3 years ago. Replaced CPS, air intake valve, temp sensor, camshaft sensor, & ignition coil. Cleaned my throttle body. I have pressure on injectors. Checked the distributor cap, looks good. I replaced cap, rotor, & wires after I got the jeep, about 5 years ago. What else do I need to check or replace to fix code 54. I’ve disconnected neg. cable but it won’t clear code. Could my O2 sensor be bad? Suggestions welcomed. [/QUOTE]
