FI & OBD2 Decoder

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

Launch Full Aprilia DTC Engine→

Code P0105Manifold Absolute Pressure (MAP) Sensor

Intake air pressure sensor electrical fault or vacuum hose disconnected.

Test: Check 5.0V VRef and sensor output 2.5-3.0V at atmospheric pressure.

Code P0115Engine Coolant Temperature (ECT) Sensor

Coolant temperature sensor circuit open or shorted out of range.

Test: Measure NTC thermistor: ~2.5 kΩ at 20°C (68°F), 300 Ω at 80°C (176°F).

Code P0120Throttle Position Sensor (TPS / APS)

Ride-by-wire dual potentiometer track correlation fault.

Test: Measure APS Track 1 (0.8-4.2V) and Track 2 (0.4-2.1V); verify smooth 2:1 ratio.

Code P0335Crankshaft Position Pick-Up Sensor (CPS)

Zero timing pulses detected from VR sensor during engine cranking.

Test: Measure inductive pickup coil resistance: 560-680 Ω across 2-pin connector.

Code P0505Idle Speed Stepper Control

Idle air bypass stepper motor position error or vacuum leak.

Test: Clean stepper valve bore; perform Marelli / Bosch ECU adaptation reset.

Code P1600CAN Bus Line / Dashboard Comm Timeout

CAN communication lost between Magneti Marelli / Bosch ECU and APRC IMU / TFT Dash.

Test: Measure 60 Ω CAN termination resistance between CAN-H and CAN-L with ignition off.
