i have a 2000 C5 Corvette
So this code is giving me a headache idk what it is so I can use some help guys.
Question: If it is the check valves wouldn’t I get a P1415/P1416 code?
I have one symptom that started recently (Weak acceleration) I have an automatic and when I put it in first it doesnt even move if i give it gas it slowly moves. In drive it is a little better but still weak.
I tested the SAP but its working fine it sucks and blows air good it even still has a little kick to it.
I checked the Vacuum hoses from drivers side they are fine.
So does that just leave the check valve behind the Intake Manifold and the Vacuum line going from SAP to Vacuum?
First off include the year and mods you have in your profile since there can be wiring differences year to year...the 0410 can be the air pump, solenoid, wiring, or shut off valve !!...don’t know how much electrical troubleshooting knowledge you have so I’ll hold off on that !!

oh crap sorry idk how i forgot that. Its a 2000 C5 Corvette Automatic Transmission all stock
thats good to know, where would the Solenoid and Shut off valve be located?
Solenoid is above the PCM and the shut off or diverter valve is connected to the pump !!...2 part vid to help you understand the system... if you don’t understand how it works you can’t diagnose it !!

This is out of the FSM for my ‘01...DVOM, bidirectional scan tool,12 volt test light
and a Mityvac (for vacuum testing) is what’s really needed for an accurate diagnosis !!

Damn this is good info. Ima take a look at these to help me.
Thank you I appreciate it!
So far as I know, the secondary air system, working or not, will not cause sluggish or weak acceleration. It will throw a code and trigger the check engine light but not affect the way the car drives.
I suggest clearing all existing codes and then drive the car and report back on any new codes and symptoms.

I actually did start getting a C1243 code recently saying service ABS/Traction Control you think thats what would be causing the weak acceleration? Those are the only two codes I have right now.

The C1243 is an ABS pump motor that is “stalled” or not operating correctly...will not cause weak acceleration...you CAN wait till a rainy day and find a big parking lot or deserted open road and STOMP on the brakes a few times when you’re hauling down the road..this may make to pump start working again !!...I use a bidirectional scan tool that is able to turn on the pump and I do this maybe every few months !!...now as far as the “weak acceleration” this can be a few things...you really need a scan tool to see what’s going on...I’d be looking at your fuel trims, O2 sensors, and MAF and MAP sensor..you can even try disconnecting your MAF sensor and see if the weak acceleration goes away...it will set a code only because it’s disconnected but you can always erase it through the DIC !!..I also included the AIR wiring if you need it !!

Ok awesome, this was very informative, im going to try that for the ABS and Ill try the sensors too fingers crossed that will help me find whats causing the weak acceleration. Thank you I really appreciate it!
P0410 Code: So the problem was the vacuum line coming from the Diverter valve that runs thru the front of the car all the way to the Vacuum Solenoid behind the Passenger side Fender. My guess is there was a leak, I replaced it and problem solved and also passed my smog.
C1243 Code: I couldn’t fix this one, I did the hard braking/lock up wheels to make the ABS work but it wouldn't work. I was going to try the solder fix but apparently the 2000 models you cant fix them. You have to buy the entire part and Id rather not spend $1000 for a used ABS Motor.
Weak Acceleration/Slow movement in Drive: I found out It was the MAF Sensor. It was pretty dirty. I had put in a K&N Air Oiled Filter a while back and I think it made some debris stick in the honey comb vent.
Thank you guys! I couldn’t have done it without your informative help. You guys were awesome!
P0410 Code Not Secondary Air Pump
