MoTeC's LTC NTK (Lambda to CAN module) monitors, controls and diagnoses an NTK Lambda sensor, transmitting Lambda readings on a CAN bus.

When using multiple LTC NTKs, up to 32 Lambda sensors can be configured on a single CAN bus for simultaneous monitoring by an ECU or logging device.


  • Provides accurate Lambda measurement, even when exhaust gas temperature is changing rapidly (heating or cooling).
  • Calibrated by the user for a particular sensor using the initial sensor factory calibration, the free air calibration or the referenced gas calibration.
  • Pre-configured to suit a single unit installation. If necessary, the configuration can be adjusted; see the Configuration section for more details.
  • Units marked with a 2 or higher under the barcode are able to transmit extended Lambda values (Rich Lambda).


  • 1 x NTK Lambda sensor (MoTeC #57007)
  • Power supply voltage 11 V - 16 V
  • Power supply current 110 mA typical plus the sensor heater current. Heater current is typically 0.5 A - 1 A and up to 2 A on startup.
  • 1 x CAN — using LTC Manager, configurable to:

    125 Kbps, 250 Kbps, 500 Kbps or 1 Mbps

  • Dimensions: 38 x 26 x 14 mm, excluding wiring looms and connectors
  • Weight: 62 g
  • 1 x 4 pin male DTM connector (power/CAN)
  • 1 x mating connector for NTK Lambda sensor
  • Maximum ambient temperature: 100 °C
