Frequently Asked Questions
What does P2019 mean?
P2019 means the Bank 2 intake manifold runner position sensor circuit is reading below the expected voltage, typically from a short to ground in the wiring or a bad sensor.
Can I drive with a P2019 code?
Short-distance driving is safe. The PCM will use default values, resulting in minor performance reduction.
How much does it cost to fix P2019?
Typical repair costs range from $100 to $350, with wiring repairs being less expensive than a full sensor replacement.
