FAQ
Do I need to program the sensor after install?
No special programming is typically required. Clear codes and perform a short drive cycle so the ECU can adapt.
Will this fix low boost or limp mode?
If the issue is caused by a faulty MAP signal, replacing the sensor often resolves it. Mechanical turbo or leak issues will require additional diagnosis.
Does this include bolts or a pigtail?
No—this listing is for the sensor only. Reuse your factory hardware and harness.
