Haven't checked the codes in my car for a while but checked it with my Durametric today and found this :

P0160
Porsche fault code 20 - O2 sensor behind CAT.conv.
Bank 2

Car has been running fine and still does but has had a little occasional misfire on idle when warm??????

Could this of been the cause?????

Whats best course of action ? Replace sensor ?
Any tests?

 

Just to add

The occasional misfire was on cylinder 5 which I believe is bank 2.

Plug and coil was changed but made no difference

 

Well P0160 is a type 2 error meaning no signal....either it is has a poor connection (loose/corroded), disconnected (signal or ground wire) or its dead. You can test it using a data logger, but without that, I would check connections, if they are OK replace the sensor.

 

I have the durametric software. What data boxes do I need to tick ?

Also am I right in thinking that bank 2 is on the right hand side if you look at the engine from the rear?

 

Bank 2 passengers side

 

Cheers mate

 

Wross, you are just a wealth of information..

 

Done some datalogging and found this. Appears the 02 sensor on bank 2 has no resistance? Does this confirm its faulty?

O2 sensor resistance behind cat bank 1 = 0.99 to 1.00

O2 sensor voltage behind cat bank 1 = 0.88 to 0.89

O2 sensor resistance behind cat bank 2 = 0 to 0

O2 sensor voltage behind cat bank 2 = 0.69 to 0.74


Just want to be sure before I buy a new O2 sensor

 

well...could still be loose/bad wire...if you have checked all the wiring...then the sensor could just be bad

 

where can i get one of the Durametric units?

 

www.durametric.com

have a look on ebay as well

 

Just had a good look round at the wiring and it all looks solid. Its a 2001 model and the sensor looks a bit tired , covered in rust.

Think I'm going to replace it
