Malibu hybird 2008 /service traction /engine power reduced

The torque converter clutch circuit may be at fault. The best way to determine the problem is to have a scanner/computer to read check engine codes.

SOURCE: reduced engine power on

The traction control uses the speed sensor in the transmission and the wheel speed sensors to determine wheel spin. If a wheel spins braking is applied to it so that the power can be transferred to the other wheels. At some point the ECU detected a gross disagreement between the sensors and so as a precaution has entered into a limp home mode. On some systems if the fault is in error it can be cleared by putting the car into drive and moving forward a meter, putting in reverse and going a back a meter and doing this three times. If one or other of the sensors are faulty this process will not allow the error to be cleared. You need to check or have checked the error codes and the speed sensors.

you could have a stuck switch .....check your traction control switch on your dashboard....engage and disengage it , while paying attention to the rpms...notice any change...if you do notice a change, then replace the switch....if no change, it is probably on the trans itself and should not be a dealer only fix....your local reliable trans shop should be able to fix you up without emptying your entire wallet.

SOURCE: Tow messages appear on the dash board: Service traction control and Engine power reduced. When this happen I can feel the shift in the transmission when I'm driving. After a while these messages d

Pretty much tells you the system with the fault

Traction Control is embedded into the abs braking
system, so diagnose that using the codes you have,
same as any other obd codes you get

The Reduced Power could be another problem & it
cuts off fuel injectors to save the exhaust converter
from overheating & being ruined
