nissanjuke Posted February 23, 2015 Share Posted February 23, 2015 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 Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted February 23, 2015 Share Posted February 23, 2015 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.

Stutopia Posted February 23, 2015 Share Posted February 23, 2015 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/ Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted February 23, 2015 Share Posted February 23, 2015 Yeah not sure about that but I get the exhaust thing a fair bit. Quote Link to comment Share on other sites More sharing options...
