Question

2002 Nissan Altima 2.5L with code P0507. How do u check the throttle control valve to determine if it is good or bad?

Answer 1

If you get the code, then it's very likely that the you have a faulty Throttle Body. You could try cleaning the throttle body, adjust engine idle and erase engine code. If the code comes back you may have to replaced the Electric Throttle Control Actuator (Motor) to repair the problem.
