OBD codes which come up,every so often

[nissanjuke]

I have a full milltek system with decat pipes on a 2005 roadster and ever so often,engine lite comes on,then I check it with my reader and it states the following-

 

1-02 sensor 2

2-engine coolant sensor

3-cat pipe sensor

 

Is this happening due to my exhaust system as I cannot find anything wrong,temp guage sits at halfway mark all the time once it is warmed up,car runs sweet.

 

ANYBODY ANY IDEAS?

 

CHEERS

Just jot the codes down and google/forum search.

Happens to me with the cold weather at times, thus I kept the reader in the car, erase errors. I think there's some bung thing that Clark or Tarmac sell for £10.

The coolant sensor one is a bit weird if you've only changed the exhaust isn' it?

 

There's a list of codes here if you want to double check: http://www.350z-uk.com/topic/81962-350z-fault-codes-in-pdf/

Yeah not sure about that but I get the exhaust thing a fair bit.

THANKS LADS

I have a code reader,the codes that come up are-

 

P1166-HEATED 02 SENSOR 2

P0116-ENGINE COOLANT TEMP CKT RANGE/PERFORMANCE

P0420-CATS EFFICIENCY BELOW THRESHOLD

 

 

I just clear it as I cant find anything wrong,its not due a service till 45,000 miles,its at 40,000 miles at present and is only due an oil/brkepad change in march.
