Re: Grande Punto 1.3 multijet

Try unplugging large current consuming actuators 1 at a time. I.e EGR and throttle body motors to see if any of them stop this from happening it's rare but I have seen them leak unwanted voltage into an ECU and cause it to misbehave. Maybe even injector cut off test using scan tool may help. I trie...

Re: Grande Punto 1.3 multijet

Hi, don't really know the set up of this engine. I am guessing right now, maybe you got an harmonic balancer which is seperating ? Just an idea Hi Speck, good idea but CKP sensor is located on gearbox housing and reading signal from toothed wheel on other side of crankshaft. According to VIN it doe...

Re: Grande Punto 1.3 multijet

That is all very well seeing a drop out of crank signal whilst cranking and not seeing it on the other car but this doesn't explain why the car cuts out when running (You might be concentrating all your effort on this event unnecessarily) I would focus more on that injector issue that kona pointed ...

Re: Grande Punto 1.3 multijet

How do I see your problem: Your sensors totally OK! Here's a look: Event 1 - no injection. Event 2 - no working stroke and slowing down of rotation speed. The speed decreased - the amplitude (voltage) decreased. Your problem is skipping the injection. Record the "+" from the injectors on one channe...

Re: Grande Punto 1.3 multijet

Are you measuring the signal at the ECU? If so have you tried the pin fitment test between ECU and wiring harness multiplug. I find a screen wash jet unblocking tool works well. Just gently drag it in and out of the female terminal and compare the slight resistance felt to the other terminals (Defi...

Re: Grande Punto 1.3 multijet

Hiya looks like an amplitude problem to me,either the air gap is incorrect or the sensor is cracked or damaged causing the air gap to increase lowering the signal amplitude,you can get similar fault on ac wheel speed sensors,it does nt have to be much,it could even be a dual mass fault with a parti...
