DR-6A Fault Code 23 Charge Temperature Sensor

1. With diagnostic read-out tool connected to engine harness connector, disconnect charge temperature sensor connector.
2. Place system in Sensor Test Mode 03. Note that display readings must be divided by 10.
3. If display reads 5 volts, proceed to Test 6 step B. DR-6B Charge Temperature Sensor Signal Circuit
4. If display on read-out tool reads zero volts or reads zero volts then increases, replace logic module. Before replacing logic module, ensure wire of cavity 25 of blue connector is not shorted to ground.
