PaulC73 Posted May 4, 2019 Posted May 4, 2019 Hi all New to here and hoping for some help with an issue with my Insignia I have been getting fault code P0402 intermittently for a while now. I have a bluetooth OBD reader so can cancel the code. I have replaced the EGR valve and also had the intake manifold taken off and all cleaned out The code is still coming up and i have been told now it can only be the EGR temp sensor Can anyone tell me where this is located as i would rather change it myself than pay someone to do it as it is only a screw in sensor? Also if anyone might know is it worth cleaning it or replacing straight away Thanks in advance all Quote
siggyv6cdti Posted May 6, 2019 Posted May 6, 2019 Hi welcome to the club generic egr valve/sencor/dpf related... My saab 93 use to pop this code up a lot.. Did egr clean plus cleaned any sencers and did about 5 forced dpf regens over a month,, i sold yhe car on after that so unsure if it was cured.... You might get a better read out using opcom vauxcom etc as it communicates properly with the canbus Quote
