Title: SMT APS sensor repair
Post by: Anonymous on December 7, 2012, 11:25
My Toyota MR-S no longer responding to the gas pedal, the cause of failure was in the APS sensor  new APS in Russia worth $ 580  s:scared: :scared: s:scared:    to order 18 days from Japan! Because it is expensive and a long wait, I decided to fix a broken sensor.
1.remove the throttle assembly and unscrew 4 screws APS sensor and remove it
