The secondary TPS (sensor B) has a circuit fault. Modern drive-by-wire systems use two TPS for redundancy.
TPS B voltage is above maximum expected.
TPS voltage is below minimum threshold. The ECM cannot determine throttle position accurately.
Frequently Asked Questions
- Why does my car go into limp mode?
- When TPS A and TPS B disagree, the ECM cannot trust throttle position, so it limits power to prevent unintended acceleration.
- Is P0222 expensive?
- If the throttle body needs replacement, expect $100-$250 DIY. Some vehicles allow TPS-only replacement for less.
