P0C1ADrive Motor B Torque Delivered Performance

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
P0C1A compares the torque command for motor B with the torque the motor control processor calculates as actually delivered. GM's 2016, 2018 and 2019 tables set it when the difference exceeds 132 Nm for 0.1875 s in a 0.2 s window, Type A, one trip, and only while listed resolver and motor control faults are inactive. The 2011 Volt and 2012 two-mode tables also list it, the trucks with a three-phase current sum above 110 A. Chrysler documents it on the 2017 to 2023 Pacifica Hybrid: with resolver codes P0A3F, P0A43 or P0A45 it points to a short in the internal wiring connector of the eFlite transmission, which is replaced. P0C19 is motor A. Expect limp mode.
What you may notice
  • Malfunction indicator lamp
  • Vehicle in limp mode with reduced propulsion
  • Hybrid system warning, engine runs more often
Likely causes
  • LikelyShort in the internal transmission wiring connector (Chrysler Pacifica Hybrid 21-008-23)
  • PossibleImplausible rotor position signal from the motor B resolver
  • PossibleHybrid control or inverter module software requiring an update
  • RareFaulty phase current sensing for motor B
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
