P272B Transmission Range Select Motor Control Circuit Current Too High

P272B flags excessive current in the circuit of the range select motor, normally caused by a winding or wire shorted to supply. On the 2022 Mitsubishi Outlander with CVT, Mitsubishi checks this with ignition on: when one of the two phases that should be energised shows the non-energised voltage level (9-16 V instead of about 0 V), the code is set. The service text lists short circuits to power on either the A or the B winding, the connectors or the electric shift module as causes, so the code does not prove which winding is at fault. Unlike the open-circuit code P272A, the fail-safe is drastic: shifting is prohibited and the powertrain goes to neutral. The MIL comes on, and the yellow shift warning depends on road speed.

Likely causes

Motor coil A or B phase shorted to power
Damaged harness between shift module and actuator
Electric shift control module fault

Symptoms

  • Vehicle stays in neutral, no gear can be selected
  • MIL and shift system warning
