Coolant temperature sensor 3 is a third NTC coolant sensor on engines with thermal management or split cooling circuits; its position is defined by the manufacturer – on Jaguar Land Rover's 2018–2019 Ingenium petrol engines it sits in the engine block water jacket, on Audi's 3.0 TFSI V6 it is part of the thermal management. As with every NTC sensor, a low signal voltage means hot and a high one cold. CARB requires such additional sensors to be monitored from model year 2019 onwards. P01E6 means the signal voltage sits near the reference, so the module would read very cold coolant (around −40 °C) – typically an open signal or ground wire, a loose connector with poor terminal tension, an open sensor or a short to voltage. Jaguar Land Rover documents the code on its 2018–2019 Ingenium petrol engines and has the wiring checked first, then the sensor replaced.

Likely causes

Signal or ground wire open, connector loose, poor terminal tension
Sensor open internally
Signal wire shorted to 5 V or 12 V
Control module

Symptoms

  • Check engine light on
  • Coolant temperature or cooling fan behaviour possibly affected
  • Often no change in driving
