2000 Chevrolet Blazer Q&A

2000 Chevrolet Blazer Question: Is there a way to test the Throttle Position Sensor?

My Blazer shifts hard into third gear. Is there a way to test the Throttle Position Sensor or the Transmission control solenoid before replacement? -
Answer 1
Scanner needed, TPS knows nothing about which gear it's in or shifting into, although it will affect ALL gears and shifts!! Again scanner needed to check trans module! -
