Pin Voltage & Sensor Operating Ranges
Volkswagen; Corrado, Fox, Golf, Jetta, Vanagon
NOTE: Cabriolet pin voltage and sensor operating range charts are
not available from manufacturer.
INTRODUCTION
Pin voltage charts are supplied to reduce diagnostic time.
Checking pin voltages at the ECU determines whether it's receiving and
transmitting proper voltage signals. Charts may also help determine if
ECU harness is shorted or opened.
NOTE: Voltage readings may vary slightly due to battery condition
or charging rate. All voltage tests should be performed with
a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm
input impedance, unless stated otherwise in testing
procedure.Fig. 1: Typical ECU Terminal Pin Connector
