DR-2B MAP Sensor Circuit In Logic Module
1. Connect diagnostic read-out tool to engine harness connector, then disconnect MAP sensor connector.
2. Place system in Sensor Test Mode 08. Note that display readings must be divided by 10.
3. If display reads five volts, proceed to Test 2 step C. DR-2C MAP Sensor Signal Circuit to Logic Module
4. If display reads zero volts, replace logic module. Before replacing logic module, ensure wire in cavity 19 of blue connector is not shorted to ground.
