What are the symptoms of GMC Terrain p0411?
P0411 can cause a few symptoms, and can affect the drivability of your Terrain. The most common symptoms include: Backfiring- If the AIR system is not running right, the extra fuel vapor in the exhaust can combust under hard acceleration. Typically, there are three main components to the AIR system.
What does p0411 mean on an Audi A4?
By definition, the code is letting you know that the ECM has detected incorrect flow in the secondary air injection system. The secondary air injection system injects air into the exhaust to help lower emissions. Most of the time, P0411 is going to be caused by a failure in this pump or the one way check valve.
How to check for p0411 GMC secondary air injection system insufficient flow?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. How much do you know about cars? The cost of diagnosing the P0411 GMC code is 1.0 hour of labor.
What causes a Chevy Equinox to throw a p0411?
The AIR pump itself is the most common cause of P0411. They are relatively affordable. If they are no longer accepting instruction from the ECU, P0411 will be thrown. An exhaust leak can cause the ECM to think that the AIR system is not working right.

What should air pressure be in DTC p0411?
During phase 1, DTCs P0411, P2430 and P2435 run and both the secondary air injectionpump and the solenoid (shutoff and check) valves are activated. Normal secondary airfunction occurs. Expected system pressure is 5–13 kPa (0.7–1.9 psi) above BARO.
