Guys and gals, I've got two fault codes on my 2000 Dodge Dakota. It is a 4.7 V8 4X4 Quad-Cab. It has had these fault codes for years. It has just shy of 250,000 miles on it. I clear the codes and they stay gone as long as I start the engine, put it in gear and drive. If I warm the engine even for a few seconds the check engine light comes on. The only two codes are P0135 and P0155. I have checked the wiring, cleaned all four sensors, checked the fuses and relays. All seem okay. I have read quite a bit on how it probably isn't the sensors but one of the above mentioned checked items. Is there a bench test I can do, like an ohm test, that will tell me for sure before I go and spend the money on new sensors? Any ideas? TIA
