1 Answer

The SAI (secondary air pump) comes on for 30-45 seconds when you first start the engine if the coolant is under 85 deg F. It pumps air through the head into the exhaust. It's purpose is to supply extra oxygen to the cats to heat them up quicker and reduce emissions. It should have no real effect on engine performance, but does help bring engine temps up quicker making the engine more efficient.

I have a 2000 BMW 323ci with P1421 and P1423 codes


Here you go:
P1421 - Secondary Air System malfunction
P1423 - Low flow limit check
This indicates a problem with your secondary air system.
The secondary air system works during a cold start to help the catalytic converter reach operating temperature faster thus burning cleaner. You probably won't feel a difference in how the car drives however you should address these codes. It may be a faulty air pump, solenoid, torn hose or valve.
The secondary air system does not affect engine performance, it basically keeps emissions lower during cold starts on the engine.
You should visually inspect the area for a broken/cracked hose. If no hose is broken, you will likely need to replace the secondary air pump or solenoid.

I replaced my secondary air check valve on my 2001 chevy tahoe but code 1416 still comes up. what else can i check


here is what i found on p1416.



P1416 Chevrolet
P1416 Chevrolet - Secondary Air Injection System Bank 2
Possible causes
- Faulty Secondary Air Injection (AIR) pump
- Secondary Air Injection check valve bank 2
- Secondary Air Injection (AIR) pump electrical circuit fault
- Blocked Secondary Air Injection (AIR) system

When is the code detected?

The P1416 code is set when no O2 sensor voltage change is detected by the Engine Control Module (ECM).


Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)


P1416 Chevrolet Description
An Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The Powertrain Control Module (PCM) monitors the HO2S voltages to diagnose the AIR system. During the AIR test the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.

Why does my engine stop when I apply the foot brake


Check your air intake systems as they are usually an issue when it comes to braking and engine performance. If they are faulty then you probably have to replace them. Remember air intake systems can generate many problems as far as your engine performance is concerned. You can follow my AFE Performance to find out more on air intake systems and their operations..

What does this code mean? P0410


Diagnostic Test Code (DTC) P0410 indicates that your secondary air injection system is not functioning properly.
Not all 2001 Chevrolet Bazers are equipped with secondary air injection. The secondary air injection system was added to vehicles that were to be sold in certain areas where the emissions laws required it, like the State Of California.

The Powertrain Control Module (PCM) monitors the system by commanding the secondary air blower motor to run and the air injection solenoid to open. This causes additional oxygen to enter the exhaust system. The PCM then monitors the signal from the oxygen sensors to see if the commanded air has in fact, entered the exhaust system. Code P0410 sets when the PCM has commanded the blower motor on and the solenoid open and there is little or no change in the oxygen sensor signal.

GM has had some problems with these systems and there has been a Technical Service Bulletin (TSB) issued that addresses some of the known concers. Below is a brief description of the TSB and the issues involved.

Bulletin No.: 04-06-04-015A
Date: November 28, 2006
TECHNICAL
Subject:
LN2, L43 or L35 Engine SES/MIL Light Illuminated, AIR Pump Ingesting Water and DTC P0410 Set (Replace AIR Pump and Inlet Hose Assembly)
Models:
1999-2003 Chevrolet Blazer, S10
1999-2001 GMC Jimmy
1999-2003 GMC Sonoma
1999-2001 Oldsmobile Bravada
with Vortec 2.2L I4 or 4.3L V6 Engine (VINs 4, 5, W - RPOs LN2, L43, L35)
Condition
Some customers may comment on the SES/MIL light being illuminated. Upon investigation, the technician may find a DTC P0410 indicating that there is a concern in the secondary air injection system.
Cause
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump.
Correction
Replace the AIR pump and install a new inlet hose and solenoid tube assembly...

The bulletin goes on and gives detailed information on how to perform the repair and the part numbers of the replacement parts needed to do so. Your local dealer can provide the parts for you and you can probably get them to print out a complete copy of the bulletin for you. It is not really hard to do if you want to do this yourself.

2002 VW Passat GLS 1.8T throwing two codes: P0171 and P0411. No noticeable loss in performance. Can I fix this myself?


System Too Lean (Bank 1)

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.

P0411 Secondary Air Injection System Incorrect Flow Detected, check the...Combination valve
...Secondary Air Injection pump motor
...Secondary Air Injection solenoid valve
I would take it to a mechanic

1998 328i.. Got a 1421 and 1423 code...not sure where to start...


1997 BMW 328I 2.8L Customer Concern: MIL is on with trouble codes P1421 and P1423, for incorrect secondary airflow on both cylinder banks. Tests/Procedures: 1. Perform a functional test of the Air Injection Reaction (AIR) system. Tee a vacuum gauge into the vacuum hose attached to the diverter valve, located on the cylinder head towards the front of the engine.

2. Allow the vehicle to sit over night. Start the engine (cold) while monitoring the amount of vacuum on the gauge at startup. At temperatures from -10 to 40 degrees Celsius, there should be at least 17 inches of vacuum. At the same time, the AIR pump should run and pump a large volume of air into the exhaust. Potential Causes: A.I.R. Pump
Air Pump Relay
Restricted Cylinder Head
Diverter Valve
Tech Tips: These codes are related to a problem detected in the Secondary Air Injection system. Scan tools with BMW software include a feature to command the AIR pump on and off. The pattern failures for these codes are the AIR pumps due to leaks in the diverter valve and moisture or condensation in the AIR pump.

Possible fix but not all items. Just areas to look at:
Confirmed Fix - A.I.R. Pump - A.I.R. Diverter - A.I.R. Pump, Air Injection Reaction Diverter (AIRD) Valve - Air Injection Reaction Diverter (AIRD) Valve - Check Valve, Secondary Air Pump - Diverter Valve Vacuum Lines
