What are the codes for secondary air injection system?
If it does not see the short term fuel trims rise, then the PCM interprets this as a malfunction in the AIR system and a code will be recorded. Other secondary air injection system trouble codes include P0410, P0412, P0413, P0414, P0415, P0416, P0417, P0418, P0419, P041F, P044F, P0491, and P0492. Symptoms of a P0411 DTC may include:
What do you need to know about a secondary air pump?
If you’re wondering what a secondary air injection pump is, you’re not alone. In this article, we’ll go over the purpose of the secondary are pump as well as the symptoms you should watch for that indicate the pump is failing. What Does a Secondary Air Pump Do? What Does a Secondary Air Pump Do?
Where is the air control solenoid valve located?
The AIR control solenoid valve/pressure sensor assembly-The AIR control solenoid valve/pressure sensor assembly has a solenoid mounted valve.
When to replace a secondary air injection pump?
If you’ve already experienced engine stalling, poor acceleration, and a check engine warning light, then you need to have the secondary air injection pump checked out immediately. If it is proven to be the problem, have it replaced by a certified mechanic.

How does a secondary air injection system work?
This component is also called a smog pump, or an air pump, and it lies within the secondary air injection system of the vehicle. It can reduce carbon emissions by pumping fresh air from outside into the exhaust stream. By the time fumes leave the tailpipe, there are fewer hydrocarbon pollutants in them.
If it does not see the short term fuel trims rise, then the PCM interprets this as a malfunction in the AIR system and a code will be recorded. Other secondary air injection system trouble codes include P0410, P0412, P0413, P0414, P0415, P0416, P0417, P0418, P0419, P041F, P044F, P0491, and P0492. Symptoms of a P0411 DTC may include:
When to suspect a bad air pump relay?
If not, check for power and ground present at the AIR pump when jumpered. If there is no voltage/ground present at pump repair open in wiring harness. If voltage and ground is present, but pump still does not run, suspect a bad AIR pump. If after jumpering the AIR pump feed circuit the pump activates then the problem is likely the AIR pump relay.
What is the p0411 secondary air injection code?
Other secondary air injection system trouble codes include P0410, P0412, P0413, P0414, P0415, P0416, P0417, P0418, P0419, P041F, P044F, P0491, and P0492. Symptoms of a P0411 DTC may include: Backfiring in the exhaust under hard acceleration Engine running rich (This is counter-intuitive. See explanation below)
What does the OBD II fault code p0418 mean?
What Does Code P0418 Mean? OBD II fault code P0418 is a generic code that is defined as “Secondary air injection pump relay A -circuit malfunction”, and is set when the PCM (Powertrain Control Module) detects a failure or malfunction in the SAI ( S econdary A ir I njection) circuit that is associated with the relay labelled “A”.
