This makes it a pain to troubleshoot because you can’t just look at one spot to figure out what’s going on.įor starters, there are a litany of different sensors that can fail and cause a P0299 code. While the end result of a P0299 is pretty straightforward, you can get there in tons of different ways.

Increased fuel consumption (due to a lack of performance).

Lack of boost from the super/turbocharger.

Outside of the obvious check engine light, the most likely thing you’ll notice is a decrease in engine performance.Ī P0299 turns on when your turbo isn’t producing enough boost, so it’s no surprise that performance will suffer, especially when you’re trying to achieve peak power.įurthermore, you might notice that you’re burning through fuel a little quicker than usual, but that’s just because you have to hit the throttle a bit harder to get the results you’re used to.

The component does its best to oblige, and another sensor measures the performance and reports the actual boost achieved to the PCM. The process starts when the PCM sends a signal to the turbocharger or supercharger to produce a specific amount of boost. More specifically, it’s not producing enough boost when the PCM tells it to, or at least the PCM doesn’t think it is.

Underboost is a fancy term for your turbo or supercharger not performing as it should. Turbocharger/Supercharger 'A' Underboost Condition
