Shop Lexus GS300 Replacement Throttle Position Sensor

Lexus GS300 owners experiencing throttle problems where there seems to be no throttle response unless the pedal is floored may need to replace their car's throttle position sensor (TPS), which is located on the front side of the throttle body. When the check engine light comes on and reading the diagnostic codes shows a p1120 or p1121 error code, this indicates an accelerator malfunction problem that could relate to a few different things, including the TPS, although the problem could also be with the idle valve motor.

Replacing the throttle position sensor with a part from the dealership will typically run several hundred dollars, which is outrageous but may be exactly what the Lexus mechanic recommends. At PartsGeek.com, the original equipment TPS for the Lexus GS300 costs about one-third that price, with other top manufacturers offering quality replacement parts for even less. Model years covered include 1993 through 2005.

I had a thottle body diagnosed on my car that was quoted as being 1700 dollars at a shop. I looked on some forums and found that I could just replace the throttle body motor and or positioning sensor instead. I purchased the parts on here for 260 dollars or so, three years later that car is still sliding sideways. Thanks - 98 LEXUS GS300/ 2jzcrazy
