need wiring diagram of o2 sensor connections to ECU so i can do continuity test on them. had intermittent fault lights which went permanent after moving sensor plug/harness. new sensor fitted but still the same , codes are p0133 and p0134 , so sensor slow to react which leads to no activity code i assume. all help much appreciated. fuel consumption has come down as well.

 

From my North America 02 Service Manual...not sure this will be correct on RHD cars.

 

AGAIN this is from the North America version PROBABLY different for RHD cars.

 

I am unclear on what you mean by the statement. Fuel “consumption” versus efficiency can be affected by several components. Besides the O2 sensor problem, you could have an injector, fuel regulator, or fuel filter issue too.

 

thanks for this , it is because loss of oxygen sensor makes it run richer apparently. can't see them using different ecu, probably just in a different position. we will see

 

Did more checking and found the O2 continuity PDF and includes RHD schematic ....make sure to look for the RHD label.

 

thanks very much,hoping to look .at the weekend

 

Did you ever get the P0134 code figured out?
