Code 1 should be the o2 sensor.


What kind of y8 manifold is it. Auto or Manual

jspeceg

its a manual y8 manifold

Is the O2 sensor plugged in? If you reset the ECU does the code return?

jspeceg

resetting the ecu works but the code comes back when attempting to start.

lol. yes the o2 sensor is plugged in.

jspeceg

97 ex, 97 ex engine harness, y8 header, o2 is in the header, NOT in the EX converter.

What adapter are you using between the harness and the ECU? Have you verified the pins and wires are all intact? Have you made sure the plug on the O2 sensor, as well as on the engine harness are both clean and free of corrosion? Have you checked those wires?

jspeceg

wires on the jumper are fine. o2 plug is fine and clean. tried 2 different o2 sensors and 2 different ecus. all same result.

In that case, it's a problem between the ECU and the O2 sensor plug. Check for continuity on all four wires, from the plug to the ECU plugs before the adapter harness.
