Boost temp sensor (T_BOOST), short circuit to +24V or open load
βΆ How to fix
Check the connectors and wiring. Measure the resistance in the boost temperature sensor. The resistance shall be around 2.5k Ohm at 20ΒΊ C.
What you'll see
No driver-visible symptom recorded.
System reaction
The engine torque response could be affected and there is risk for black smoke.
Diagnostic depth
Detection
The voltage has been above 4.90 V. (~-40 Β°C)
Possible cause
Short circuit to battery voltage (U30) or open load.
