YEP EASY FIX CHECK FUSES TO AIR PUMP VACUUM SOLENOID.CHECK VACUUM HOSES AND VACUUM SOURCE TO THE AIR PUMP VACUUM SOLENOID .THE AIR PUMP VACUUM VALVE SOLENOID IS NORMALLY CLOSED NO VACUUM IS APPLIED TO THE CHECK VALVE. WHEN THE PCM ENERGIZES THE SOLENOID BY COMPLETING THE CIRCUIT TO GROUND. THE VALVE OPENS VACUUM IS APPLIED TO THE CHECK VALVE. THE CHECK VALVE OPENS AND AIR FLOWS THROUGH THE TUBE INTO THE EXHAUST MANIFOLD. THREE THINGS WILL CAUSE SECONDARY AIR PUMP PROBLEMS.THE SECONDARY AIR PUMP IS BAD.OR THE AIR PUMP VACUUM SOLENOID NOT GETTING VACUUM OR POWER.OR THE CHECK VALVE TO EXHAUST MANIFOLD NOT OPENING.IF YOU HAVE FAULTY SECONDARY AIR PUMP IT WILL MAKE SQUEALING NOISE AIR PUMP GETTING READY TO LOCK UP.

Code p2445 - how to repair or bypass


P2445 code definition

Secondary Air Injection System Pump Stuck Off Bank 1

What the P2445 code means

The secondary air injection system is designed to pump outside air into the exhaust in order to help reduce harmful emissions. This trouble code indicates that the powertrain control module has detected a malfunction with this system on the bank 1 side of the engine.

What are the causes of the P2445 code?

The most common cause of this trouble code is a failed air injection pump. The air injection pump is designed with a check valve inside which only allows air to flow in one direction, preventing exhaust gases from escaping through the air pump and only allowing air to enter. When this check valve fails, moisture is able to get inside the air pump. During the winter months this moisture can freeze, causing the air pump to seize up and possibly break. Other possible causes of this issue would include damaged wiring or connectors associated with the air pump, blown fuses, or a broken serpentine belt

OBD test - Emissions test


hi ecudave, i will go for a tune-up / clean up; the injection system, intake and replacing the sparks, regular maintenance like this will surely clean you emmision. as per re[air cost or shop costs, that will still depend on which part to clean or to work on or even to replace like the spark, but it will not be more than $400.

hope that helps

OBDII says secondary air injection system. What is secondary air injection system


This is a pump that pushes air into the exhaust manifold of your car. Typically when this code occurs the one way valve which prevents water from going back into pump has failed. You can usually just replace the valve to fix this problem.

Code p0410b secondary air injection system? what does it meen? what is the cause?


The secondary air injection system is an electric low pressure air pump that blows air into the exhaust stream to help burn up Hydrocarbons (HC), it only operates under certain conditions such as a cold engine. The common cause of failure is that the electric pump motor fails. The pump is sold as one complete assembly and is located under the hood of the car in the engine bay. The part is about $300 and is dealer only. Below are all the possible causes of the OBD2 fault code P0410 Possible causes - Vacuum hoses damaged.
- Air Pump inoperative. (most common cause)
- Air bypass solenoid circuit open.
- Air bypass solenoid leaking/blocked or stuck open/closed.
- Air diverter valve leaking/blocked or stuck open/closed.
Other possible causes and solutions to the code. - Visually inspect vacuum lines for disconnects in the AIR systems and visually inspect for proper vacuum line routing. Repair if necessary.
- Disconnect the air pump hose at the solenoid valve, start the engine and see if there is air being pumped

Obd code of p0411 on a 1999 ford mustang 3.8 v-6 what do I check to correct


That's s failure of the secondary air pump. It'll have to be changed. It's an emissions component meant to help with cold start emissions. It won't cause engine running trouble but at inspection time you'll fail for smog. Change it before then and you'll be fine.

Secondary air injection system malfunction with the check engine light on. The 2001 olds has 89,000 miles and is in good running condition...no other problems with the car known. Had a tune-up less than...


Basically the secondary Air Injection Reactor system (AIR) forces frech air into the exhaust system to reduce HC and CO emissions. Thats why your failing its not doing its job.I'm not sure if you have a electric or belt driven pump ,or do you have the Pulse air system that uses natural pulses from the exhaust topull air into the exhaust system.
Let me know which system you have and I'll give you the testing procedure. This is a fairly easy fix.

Diagnostic code po411


The P0410 code refers to the emissions system.
The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

In here you can find the Trouble Codes List:
The CODE mean P0411 Secondary Air Injection System Incorrect Flow Detected

Good luck!!!

410 secondary air injection malfunction code comes up


P0410 Secondary Air Injection System
"Secondary Air" is an abbreviated term for the "Secondary Air Injection System". This system uses a separate air pump and a series of metal and rubber tubes to force outside air into the exhaust stream and help the catalytic converter burn away excessive emissions.

Possible causes and fixes are:
#1 Poor connection, rubbed-through wire insulation or a broken wire inside the insulation.

#2 Inspect harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wire connection, and damaged harness.

#3 Check for worn or loose AIR pump drive belt.

#4 Check for pinched, kinked or restricted AIR pipes, hoses or fittings.

Problems with this system can stem from electrical circuits, solenoids, or switches that control the pump and valves. Other problems include sticking valves, loose, rusted, or poorly connected lines, a broken drive belt, or possibly a bad pump.
