Rev 1 o2 sensor

Post by Bish1999 »

I've checked everywhere, and cannot for the life of me find a definitive answer.

Did the UK model rev 1 MR2 have an 02 sensor and if so where is it?
It's not anywhere on my front pipe and I can't seem to find any sort of wires leading to the headers.
I know the JDM model definitely did but for the UK model there is so apparent info.
Worried If it has one it maybe the reason for my current running issues which are only occurring after the engine has warmed up and thus has left closed loop.

Update for anyone that sees this thread with the same sort of issue:
UK spec rev1 did not have an 02 sensor. The af ratio is manually adjusted somewhere on the back of the engine while it is connected to a wide band gauge.

Chap at MR2 BEN was very helpful indeed.
