I had a short circuit problem with my car because of a faulty fuse and some of the engine harness wires melted together. I repaired the harness the engine starts normally but I am getting
Signal high obd codes for the 3 MAP pressure on the engine.
B83-II is one of the MAP sensors. I measured the voltage between PIN 1 and 3 of the sensor and i am getting mVolts instead of the 5V. I backprobed the ECU pins and i got the same voltage. The voltage between PIN 3 and battery negative is indeed 5V.
My question is , should i expect 5V between PIN 1 and 3 or PIN 1 and battery negative or both?
The engine is 1.4 TSI VW.
