⚙️ Key Features

  • Sensor, 0.043 kg
  • Supersedes 20543720
  • Listed for 28 applications across TD and TAD engines

🔌 Function

Detects the monitored operating condition and sends the corresponding electrical signal to the control, alarm or instrument system.

⚠️ Common Signs of Failure

  • Incorrect, intermittent or missing instrument/control reading
  • Stored fault code or warning alarm
  • Open circuit, short circuit or implausible signal
  • Corroded connector or damaged wiring
  • Fault changes when the connector or harness is moved

🛠️ Service Notes

  • Note how the sensor sits and how its lead is routed before removing it, and support the harness so refitting does not leave the cable strained or rubbing
  • Turn the sensor with a spanner on its hex only — never lever or twist it by the connector body or the wiring, which breaks the internal joint even when the sensor looks undamaged
  • Renew the O-ring or sealing washer where one is fitted, and do not add thread sealant unless the manual for your engine specifies it; sealant on the threads can break the earth path of a sensor that earths through its body
  • Tighten to the figure in the workshop manual for your engine — overtightening distorts the housing and shifts or destroys the sensing element
  • Make sure the connector is clean, dry and fully latched home and check the pins for corrosion and spread — a poor connector accounts for a great many faults blamed on the sensor — then run the engine and confirm the reading or warning lamp behaves sensibly before returning the boat to service
