English to Portuguese Tech/Engineering Engineering (general) engine

Start the engine.
if it is expected that warm-hold should be active, check conditions for warm-hold activation before fault tracing further.
'Conditions not being met' as a result of a system drain activation attempt is an indication that system drainage is not possible due to conditions not being met. This can be the case if pressure has not been built up in the system. Pressure must have been built up in the system during the current drive cycle in order for the system drainage function to be available.
'EGR differential pressure sensor' is connected to a specially-shaped tube, which the recirculated exhaust gas flows through. The EGR flow rate (mass flow) is calculated by the engine control unit based on the value it receives from the differential pressure sensor, along with the values from the boost pressure sensor and the EGR temperture sensor.
'SET' not pressed
(Prerequisite: Engine oil temperature must be above 55癈 (131癋)).
1. Depress and release the pedal.
A fault exists in the thermal switch circuit
A frozen cycle is an event in which the last driving cycle did not conclude with a completed system drain and the exhaust temperature sensor detects a temperature of -10癈 (14癋) or less at start-up. This implies that freezing conditions were encountered while there was diesel exhaust fluid within the system.
A hot engine and/or fluids can damage test equipment and can cause personal injury due to burns.
A. Engine Exhaust Gas Temperature- Temperature of the exhaust as it enters the DPF assembly.
ABS must not be active (this signal cannot be read from the engine ECU.Check that there are no fault codes in the ABS system).
