SOURCE: how to replace EGR valve on 99 Chevy Tracker

Take off your EGR valve and clean it out with carb cleaner also
grease tyhe little screw thing in it,,, u will c what i mean if u take it apart. carbon builds up in the chamber. it is located at the back left side of your engine and is a bit of a pain to take off. this should save u the cost except for the cleaner and labor. i had the same problem cheapest i found was 90$ on ebay.

SOURCE: Secondary air supply failure

I have a 2005 Envoy with a 4.2..... Just recently the check engine light illuminated so I read the code after replacing the 20amp fuse labeled cigar. My OBDII connection had no power so if you plug your reader in and nothing check the fuse under the hood labeled "cigar"
After pulling the code P0410 Secondary Air Injection Malfunction I checked the operation of the air pump by removing the hose connected to the solenoid. By the way the solenoid is located on the pass side of the engine top towards the back. After pulling the hose off the solenoid I started the vehicle when it was cold and after 20 seconds or so the pump should turn on and blow air out of the hose. Once I verified the pump was operating I pulled the solenoid then placing jumpers from the Positive & Negative of the battery to the pins on the solenoid. You should be able to hear the solenoid click which says its operating. But mine did nothing so I read across the pins with an Ohm meter and verified the coil was good.
So take some good penetrating oil and fill the inside of the valve with it. You can see the plunger shaft assy in the opening and thats the area you want to fill with a good penetrating oil!!!! Let it sit for a couple of hours keeping it full of oil. The housing is aluminum and the shaft is likely to be a brass material so rust is not possible. Its caused by a buildup of carbon!! The penetrating oil will soften the carbon which in turn will free up the plunger!! MINE WORKS GREAT NOW and plus you will save around $140.00 if you were to buy it from the dealer!!! Or $80.00 aftermarket from RockAuto.com

SOURCE: Check engine light

Funny that they changed the temp guage sensor....known problem on pre-2001 Audi TT and VW engines. Maybe yours was an early build 2002, so they helped you avoid a future problem.
As for the air flow, another known problem is the MAF (mass airflow) sensor. Don't panic, as this is a do it yourself job. Very likely problem if you ever installed a K&N type aftermarket air filter. These oiled filters cause buildup on the sensor. Free fix is to take the sensor body off (its the big ring/pipe coming off the air filter box before the rubber air intake hose) and clean the senor with isopropyl alcohol. Sensor body comes off by loosening the hose clamp on one end, and two screws into the filter box on the other. Don't forget to release the wiring harness plug by gently releasing the tab with a flat head screwdriver.
If your not comfortable with the cleaning, just find the MAF part on-line...about $200 bucks for a new one from Bosch. Very easy to do it yourself and a common failure point on the Audi.
For those still having the coolant sensor problem, also easy to replace yourself....about $10 bucks with a new o-ring.
Like GURU said, a code reader tool will tell if you have these problems, after the engine light comes on.

Did you check to see if there is power getting to the pump? Did you check the air pump fuse? Do you have any power at the relay that you replaced? Is there any power at the combination valve? Is the computer able to ground the relay? Is the computer able to open the combination valve? Did the relay check bad? If not, why did you replace it?

The only way to effectively check the entire air pump system is with a scanner. You can perform continuity tests on every wire, but you cannot verify proper operation without a scanner. You must command the air pump on with the scanner and check to see if power is getting to the pump. Without the scanner there is no way to tell if the computer is even able to operate the relay so the pump can get the power it needs. There is most likely a broken wire or bad connector somewhere, but the only way to find this without a scanner would be to physically inspect every wire in the system manually and just hope and pray that the computer is actually sending the signal to the relay. (You will not know if it is a computer malfunction unless you physically eliminate EVERYTHING else.)

DTC P0410 sets when the PCM commands the air pump on and the combination valve open and there is no change in the oxygen sensor voltage. The problem can be in the air pump circuits, the combination valve circuits, The combination valve itself, the air pump itelf (not likely if you can get it to run with a jumper) a faulty PCM, or even rarely but possibly, clogged-up ports in the exhaust manifold. Again, a scanner is required to verify the operation of the circuits as well as to verify that the problem is fixed after repairs are made.

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.

Secondary Air Valve


the solenoids go bad all the time on those. if the pump is pumping and the valve is new, that's most likely the cause. It should be right near the valve

Newly installed EGR Valve stuck open


A code P0411 means that there is insufficient flow in your secondary air injection system, this is totally separate from the egr (exhaust gas recirculation) system. Has the vehicle been re-scanned? You should also know that if an egr valve is stuck open, the vehicle would be almost un-driveable, as it would create a huge vacuum leak.
If the same code is coming up, I would take a very close look at the hoses going to and from the injection pump. Check for any kinks or damage.

07 chevy cobalt 2.2L engine light is on steady


I also have a 2007 chevy cobalt and the check engine light has been on for about a year, so I went through Emissions and the code p2434 showed up---meaning the secondary air injector pump was bad, so now the air pump is replaced and I got it checked on a OBD scanner and it said there was low voltage to the air pump--meaning the old air pump was good and the problem is somewhere else (I checked the old pump with a volt metor)I got the code reset several times and the light still comes on. There is somethlng giving the pump low voltage and I don't know what the solution is. I may be wrong but it may be the connector that goes to the pump but I really don't know.

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
