| Pin(s) | Function | Better Verification Method | | :--- | :--- | :--- | | | Throttle Position (TPS) Signal 1 | 0.5v (Closed) – 4.5v (WOT). Slope rises with throttle. | | 21 | Throttle Position (TPS) Signal 2 | 4.5v (Closed) – 0.5v (WOT). Check this! If A and B don't add up to 5v, the ECU defaults to limp mode. | | 29 | MAP Sensor Signal | 1.0v (idle) to 4.5v (boost/atmospheric). If stuck at 4.9v, your 5v reference is shorted to ground. | | 6 | Crankshaft Position (CKP) | Variable reluctance (AC voltage). Cranking should yield >1.5v AC. If you see DC, your multimeter is wrong. | bosch m797 pinout better
