Code Description

Group 5C! displays when the Electronic Control Unit (ECU)

receives an unusually high or low reading from the PCU

Sensor. A diagnostic tool will specify 33 for a high reading and

34 for a

low reading.

for a

shorted-to-ground or an open PCU Sensor circuit.

If the circuits check out OK, secondary causes could involve a

faulty transducer

guidelines on system

diagnostics.
