Authentic factory ECU fault codes, sensor resistance specifications, and harness pinout troubleshooting.

Launch Full Triumph DTC Engine→

Code P0107Manifold Absolute Pressure (MAP) Sensor

MAP sensor circuit low voltage or condensation moisture blockage in vacuum line.

Test: 5.0V VRef at sensor harness pin 1; check SRAN 606 breather hose condensation trap.

Code P0118Engine Coolant Temperature (ECT)

Coolant temperature sensor signal open circuit or shorted high (> 4.85V).

Test: Measure NTC thermistor: 2.45 kΩ at 20°C (68°F); 290 Ω at 85°C (185°F).

Code P0122Throttle Position Sensor (TPS / APS)

Electronic throttle twist grip or throttle body position sensor low voltage.

Test: Check APS 1 (0.85-4.15V) and APS 2 (0.42-2.08V); ratio must maintain exact 2:1 correlation.

Code P0335Crankshaft Position (Pick-Up) Sensor

Zero engine speed sync timing pulses received by Keihin / Bosch ECU.

Test: Measure VR inductive pickup coil: 560±50 Ω across 2-pin harness connector.

Code P0505Idle Speed Control Malfunction

Engine idle speed deviates from target by > 150 RPM after adaptation learning.

Test: Perform Triumph TuneECU / Dealer Tool 12-minute adaptation idle reset from cold start.

Code P1600CAN Bus Pack Communication Timeout

CAN bus lost communication between Instrument Pack, ABS Modulator, and Engine ECU.

Test: Measure 60 Ω termination resistance between CAN-H (Blue) and CAN-L (Red) at diagnostic port.
