J Woody Posted March 29, 2018 Report Share Posted March 29, 2018 So, I have a Lupo 1.4S and when I drive it (starts fine), the doors will unlock and the interior light turns on, then the car will cut out (revs slowly drop to zero). It will then start up fine, drive for a few metres then cut out again, all while pretty much constantly unlocking the doors. When the car cuts out it brings the engine light on with the following codes: 16585 to 16588 - Injector Cylinder (1 to 4) (N32): Circuit Malfunction -- Intermittent 01039 - Coolant Temperature Sensor (G2) - Not currently testable -- intermittent 00945 - Crash Sensor (G190) - Short to Ground Any help diagnosing this problem would be greatly appreciated.

Sausage Posted March 29, 2018 Report Share Posted March 29, 2018 If by crash sensor it means the one that detects a crash and shuts off the fuel then that could be the cause of it cutting out, but it might be air bags or something else. Looks like electrical gremlins though either way, check the earths to body and engine / gearbox etc and dodgy wiring for starters....

J Woody Posted March 30, 2018 Author Report Share Posted March 30, 2018 I have cleaned the earths behind the left headlight and it seems to have worked. Thanks Quote Link to comment Share on other sites More sharing options...
J Woody Posted April 13, 2018 Author Report Share Posted April 13, 2018 80 miles later, and the problem has returned. There are some new fault codes: 17550 - Load Calculation Cross Check: Lower Limit Exceeded - Intermittent 17524 - Oxygen (Lambda) Sensor Heating: B1 S1: Open Circuit - Intermittent 17513 - Oxygen (Lambda) Sensor Heating; B1 S2 - Intermittent 17526 - Oxygen (Lambda) Sensor Heating; B1 S2: Open Circuit - Intermittent Along with the codes from before, which were cleared and have now returned. Again, any help would be much appreciated. Quote Link to comment Share on other sites More sharing options...
Rich Posted April 13, 2018 Report Share Posted April 13, 2018 check the wiring which goes to the front lambda, it cracks up so peel the plastic back as far as you can. also, new temp sensor. Quote Link to comment Share on other sites More sharing options...
