Question about Chevrolet Cobalt

1 Answer

2008 Chevy Cobalt w/72k - I have issues with secondary air injection. (2) days after steering recall done I start getting - Code, P0411,P2431 with P2440 - Secondary Air Injection System Switching Valve Stuck Open (Bank 1) was latest code. Think I found the problem - pump was FULL of water. Emptied best I could, tried to disassemble but (2) of T20 torx heads stripped, cut slots in them and still just can't turn them. So reinstalled and works for now (does not sound good) but my question is how did it get water in it and/or what is wrong to allow it to happen? I am pretty sure all my issues are in the pump but before I put in a new one I need to find out how to avoid it filling up again. Any reply would be greatly appreciated as of course NO WARRANTY on this item. Although I'll bet I am not alone with this issue.

I have a 2000 2.2L Sonoma that I had to replace the motor in with a 99 engine and when I did the exhaust manifold was different and I could not hook up my air pump and I now have a service engine light on all the time but it runs just fine and I even think it improved my gas mileage. You might check your air pump connections or sensor. The air pump is on the front of the engine below the ac unit. I TOO have a Hanes book but also a Chilton book because 1 covers some things the other does not

Most likely airpump check valve went bad causing electric air pump to burn out. Replace valve & air pump.

SOURCE: I have a P2442 code

This code indicates the secondary air injection pump may not be working correctly. The pump is located on the front passenger side wheel well. Turn the front wheels sharply to the right and remove the plastic cover on the wheel well. Don't waste time trying to preserve the plastic clips. It takes a special tool to remove them and it is easier to purchase new clips at Auto Zone for $3.99 a pack.

The pump is bolted on using three 12mm bolts. Remove the inlet tube and exhaust hose from the pump. The pump is wiring is connected directly to the motor with a two foot extension. The cable is feed through the same hole the outlet tube is in the fender well. It is terminated into a simply connector located on the front passenger side of the engine.

Remove the motor from inside the fender well. Remove the bolt located in the center of the plastic cover. Remove the bolts located on the corners of the housing. Inspect the blower for wear and moisture. Clean as necessary. Attach an extension wire to your battery. Please use caution before attaching them to the fan wires. The fan spine at high RPM's and it may startle you at first. Obviously if the fan turns it works move forward. If it doesn't there may be binding, carrions, or the motor is burned out. Inspect and repair. The worst case scenario is the small motor may need replaced.

This project will take about 2 hours to perform but it is worth your time verses the cost the dealer will charge you.

On a technical difficult scale of 1 -10 ten being the highest....this procedure is about a five.

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.

DTC P0411 : Secondary Air Injection (AIR) System Incorrect Air Flow Detected

DTC P2440 : Secondary Air Injection (AIR) Valve Stuck Open

DTC P2431 : Secondary Air Injection (AIR) System Pressure Sensor Performance
Circuit/System Description
The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. An electric air pump, the secondary AIR injection pump, provides filtered air on demand to the AIR control solenoid valve/pressure sensor assembly. The AIR control solenoid valve/pressure sensor assembly controls the flow of air from the AIR pump to the exhaust manifold. The AIR solenoid valve relay supplies the current needed to operate the AIR solenoid valve/pressure sensor assembly. A pressure sensor is used to monitor the air flow from the AIR pump. The powertrain control module (PCM) supplies the internal pressure sensor with a 5-volt reference, an electrical ground, and a signal circuit.
The AIR diagnostic uses 3 phases to test the AIR system:
DTCs P0411 and P2430 run during Phase 1
DTCs P2430 and P2440 run during Phase 2
DTC P2444 runs during Phase 3
During phase 1, both the AIR pump and the solenoid valve are activated. Normal secondary air function occurs. Expected system pressure is 8-10 kPa above BARO.
During phase 2, only the AIR pump is activated. The solenoid valve is closed. Pressure sensor performance and solenoid valve deactivation are tested. Expected system pressure is 15-20 kPa above BARO.
During phase 3, neither the AIR pump nor the solenoid valve is activated. AIR pump deactivation is tested. Expected system pressure equals BARO.
In all 3 phases, testing is accomplished by comparing the measured pressure against the expected pressure. The PCM can detect faults in the AIR pump, AIR solenoid valve/pressure sensor assembly, and the exhaust check valve. The pressure sensor can also detect leaks and restrictions in the secondary AIR system plumbing.
