I keep getting a code 34 so decided to fix the problem once and for all. The code only appears if the car has been on boost and you can feel that something isn't right. I've already checked the sensor and the resistance was spot on, so I checked the input at the ECU at idle and it was between 2 and 3 volts as it says in the manual. I decided to go for a drive with the voltmeter connected to see if it changed under boost. The car was back to its old self again, much faster and I could tell the problem had gone before I'd even checked for the fault code, which wasn't there. But as soon as I disconnected the earth probe of the voltmeter it went back to how it had been and the fault code came back. So I'm now thinking that there is something wrong in the wiring, possibly the screening wire, and the input wire being earthed through my voltmeter is somehow sorting the problem. Unfortunately I know very little about electronics and don't know what to try. Does anyone have any suggestions on what to try next?
