So i replaced my Brake pads today on my 2003 160 TF, took it for a drive around the block and my engine light has come on.
I have a cheap code reader which does read one code but displays NA 01/01 instead of a fault code.

Does anyone have any ideas please?

“NA 01/01” means “the monitor is not supported on this vehicle”. Such a shame, I was just over in Essex on Saturday and had my PScan with me. But I’m sure someone local will also have one to help you out.

Hi Kevocouk,. Are you anywhere near Romford, I have a couple of scanners and a T300 which will read your faults. Your welcome to drop by if your local

Hi, thats very kind of you, thanks. Im the other end of essex in colchester. Im going to try it with a different scanner and a bluetooth android app, ill let you know if i get any joy.

Ok no problem, let us know how you get on

So i have plugged in the bluetooth dongle, i get stored code p0141, o2 sensor heater circuit.

anyone know where i should be looking?

I had the same code when I purchased my Tf and the car is low mileage and had hardly been used. My friend reset the code and the light went out. Now as a daily driver I havent had the problem since.

OK, ill reset the code and have a drive tomorrow, fingers crossed

The heater circuit is built in to the lambda probe. It helps get the probe up to operating temp and switch over to more economical mapping quicker.

Also p0141 hints to the post cat sensor, the one in the 90 degree angle to the left of the cat. Can be a pain to remove. I usually cut the wires (unplug first!), put a “specially designed” 22mm ring spanner (other end cut off to slide on extension) onto the sensors hex bottom, heat up with a gas torch and then crack it open.

Great, thanks for that, will get it up on the ramps and take a look
