Yamaha is recalling certain 2009 Yamaha VMAX motorcycles for excessive electrical resistance in the ground wire from the accelerator position sensor (APS) and throttle position sensor (TPS). The issue, which affects 700 motorcycles, could cause the wrong signal to be sent to the bike’s ECU, resulting in an unstable idling speed, and in-turn an unsafe idling speed could precipitate a crash. The issue only affects VMAX’s built between June 2008 and March 2009.
