Re: K12 Nissan Micra P0132

If you remove only this particular wire from the ecu connector than you know for sure that the problem is not in te wiring or the connector. Unfortunately I don't know if the 2.49 volts coming out of the ecu is normal on this car. Most times the lambda wiring has an 'open voltage' of 0.45 mv. You ca...

Re: Astra 1.4 EcoTec running rich

Hello, You have to replace the katalysator. The switching of the first lambda indicates a closed loop, witch is good. Switching of the second lambda means the katalysator is not functioning. Thats also the reason that there is some hc and o2 left. Most times this wil set a fault code (p0420). But it...

Just had a look at the meassurings.
Looks to me like your sample rate is to low.
Because of this it looks like the voltage drops down when the frequense rises.

If you send me your email adres then I can send you a wiring diagram.

Re: rattling dodge intrepid

Nice case study! The Wps500 is high on my list.. I have a question about the timing. Did you took the capture of the timing at cold and warm engine at the same rpm? Otherwise the timing is not the only thing cousing changing in the time between cam and crank pulse. For example: If the time between s...
