hytech header - engine check light on ..02 sensor code

[vteccoupe]

which O2 code?

first thing to do is reset ECU & see if it repeats itself

if it does,go straight to ECUMANs sticky in the DIY forum.

will do just that.

my mechanic had removed the battery and reconnect again and still throwing the same code

how was the code read with scanner or CEL?

i repeat,what code was it?
