Exhaust re-circulation valve problem results in recall of 2,410 vehicles in Vietnam.
Toyota Motors Vietnam (TMV) has announced it will recall 2,410 Camry 2.0E vehicles produced between April 6, 2015 and April 1, 2016 to address a faulty engine control unit (ECU) for the operation of the exhaust gas recirculation (EGR) valve.
The problem can be fixed in 40 to 90 minutes, depending on the plans of each dealer. Customers with an affected vehicle will receive written notification about the recall and be invited to bring their vehicle for a free inspection and reprogramming of the ECU.
According to Toyota Motors Corporation the defect was discovered in the ECU’s EGR valve control program, which re-circulates a portion of the exhaust gas to the intake system of the engine and suppresses nitric oxide generation.
If the accelerator pedal is used frequently at short intervals a situation may occur in which the EGR valve cannot close properly. The engine may then fail if exhaust gases cannot be discharged normally. In the worst-case scenario this may cause the engine to stall while driving.
