trickyd400 Posted June 23, 2019 Share Posted June 23, 2019 Hi, I have replaced the engine speed sensor as I got a P0321 error, implausible signal, short to plus. I have changed the sensor with a new HAAS one, and had the ECU tested by ECUTesting ltd, and this came back as no fault found. I have checked the wiring for continuity and shorts to positive and ground and all checks out as expected. What I want to do now is test the old sensor I took out to see if it still good before I try changing it for an another new one from a different supplier. VCDS reports zero engine speed whilst cranking: (files attached) I'm pulling my hair out here.... help!
