'95 civic trouble code 43
Hey,
recently swapped out a 1.5 in a CX and installed a 1.5 Dx engine. Used wiring that came with the DX. I also used the ECU that came with the DX. the engine runs fine. From a cold start after a couple of miles the check engine light comes on. Came up with a code 43. Now I tried stopping engine momentarily just before the check engine would come on,and restart and light doesn't come on.
My cx engine had a single wire O2 sensor and now IL have a 4 wire unit. Does the sensor require power from a fuse,since it's a heated unit? Or is it something besides an oxygen sensor? Help! Tom
