Frequently Asked Questions
- What if both TPS A and TPS B are high?
- If both read high, the throttle may be physically stuck open. Check for carbon buildup or a stuck throttle plate.
- Can I reset the throttle body after replacement?
- Many vehicles require a throttle body relearn procedure after replacement. Some clear automatically; others need a scan tool.
