What is the code for secondary air injection?
What is the code for secondary air injection?
Depending on the car manufacturer, the code’s definition may change. As was mentioned, the secondary air injection system reduces emissions by introducing fresh air into the exhaust system.
When to use an electric pump for secondary air injection?
Nearly all modern secondary air injection systems use an electric pump rather than a belt-driven pump. Often, this setup is only used when the engine is cold to reduce emissions and bring the catalytic converter up to operating temperature quickly. The PCM monitors the secondary air injection system for faults.
Why do we need to remove secondary air injection system?
About 50% of my motivation is the fact that the SAIS system is ignorant. I have no problem with helping the environment, but replacing parts of a crappily built, unnecessary system every year just isn’t going to happen. The other 50% is the fact that this allows me to justify a tune to the wife.
What to do if your air injection pump is defective?
If you have also checked the O2 oxygen sensor and all electrical connections, it is possible that the secondary air injection pump is defective and needs to be replaced. You can either visit a professional mechanic for replacement or do the procedure at home. Open the hood of the vehicle and locate the air injection pump.
What is the diagnostic code for secondary air injection?
P0416 is a diagnostic trouble code (DTC) for “Secondary Air Injection System Switching Valve B Circuit Open”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What is the DTC for secondary air injection?
P0410 is a diagnostic trouble code (DTC) for “Secondary Air Injection System Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $70.00.
How does the secondary air injection system work?
The powertrain control module (PCM) has detected a problem in the secondary air injection system, which reduces emissions by pumping ambient air into the exhaust stream. The PCM reads the condition of the secondary air injection system in increments of pressure and flow, which translate to input voltage from sensors.
What is the p0411 code for secondary air injection?
The PCM monitors the secondary air injection system for faults. If it detects a problem, it turns on the check engine light and triggers a P0411 code. It’s worth noting that not all vehicles have a secondary air injection system. Users have reported P0411 for the following makes: Volkswagen (especially on a VW Jetta), Chevrolet, BMW, GMC, and Audi.
