Hi all,

I have had my laptop connected to my car's ecu (Ford Fiesta 2001 1.25 Zetec S) as i have been having a few issues over the last week.

I have no fault codes but the Lambda Sensors are reading the following.

I have managed to export some log files from my laptop ODB software reader and here is the results. Looks like Sen 1 is reading ok which is my thought or if anyone can put me right on this as Sen 2 shows nothing like Sen 1.

Readings are taken while the engine was upto temp and while the car was idling. Is it me or is sensor 2 not reading correct or a fault.

Sensor 1 (Voltage)


Sensor 2 (Voltage)


Sensor 1 (Short Term Fuel Trim)


Sensor 2 (Short Term Fuel Trim)
