- lambda sensor shows.

Bought a denso DOX-0101 to replace it like others on here, even though the universal one was a year old.

Checked wiring back to ECU for the 4 pin lambda sesnor and all good.

Had the ECU in my hand, completely disconnected and still holds this error! Plugged back in, never started car before, turned ignition with bridged diagnostics port and still showed up.

So im left with why wont the error go?
![](./images/smilies/spacer.gif)
The only thing I can think of is the ECU as i had the capacitors replaced on it last year and maybe that's caused the damage.

any thoughts???

And anyone with a rev3+ ECU i could borrow and test with or potentially for sale of course!
