P2E18Intermediate Shaft Selection Actuator Position Sensor Circuit High

P2E18 indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the signal circuit of the intermediate shaft selection actuator position sensor. This sensor reports the physical position of the actuator that engages or disengages the intermediate shaft, often part of a disconnecting stabilizer bar or four-wheel-drive system. The PCM sets this code when the sensor signal voltage exceeds the expected range for the current operating conditions.
