2004 Toyota Tacoma Owner Comments

problem #1

Oct 202009


  • 67,000 miles


My 2004 Toyota Tacoma has an intermittent problem with a loss of power, I.e. when I step on the accelerator, it fails to respond for a brief period of time. It is a problem when pulling out into traffic, as the loss of power has led to several near collisions. The vehicle has been to the dealer twice to diagnose the problem, without a clear cause, according to the dealer. Research through an independent service shop points to a problem with the accelerator pedal position sensor. Research on Toyota Tacoma forums online also seem to support this. The only viable fix seems to be to replace the entire throttle body, since the sensors are not available separately. This cost is over $1200, as opposed to a $70 sensor. The problem is intermittent, and can happen many times a day, or be absent for weeks at a time. Three times it has resulted in a check engine light, with a tps fault recorded (the tps and apps are read as a unit by the ECU). The problem has not yet been adequately addressed.
