P0299 Code for underboost, no loss of power

B to Mechanic Advice@gearhead.townEnglish · 1 year ago

2016 Civic 1.5T. CEL for P0229/ turbo underboost. I only get one bar in the boost gauge, but no loss of power. Any idea what could be the cause? Loose clamp, hose?

Keep discussion friendly, civil, courteous, and professional. We’re here to help so being rude won’t help. Don’t assume a shop is trying to “rip you off.” It’s okay to ask for a second opinion.
