Pulled Codes: P1457, P0410, P0122
My CEL came on 2 days ago and I'm getting a rough idle, even two stalls. Now the car is at least idling better and not stalling. I went to Autozone and they pulled the codes for free with the OBD II tool.
My private Honda mechanic, he is much cheaper and better than the dealerships, is out of town for 2 more days. Is it ok to drive the car with these codes until he gets in town?
P1457- "Unable to pull vacuum in tank"
P0410- "The PCM has determined that a malfunction exists in the secondary air injection system."
P0122- "The PCM has determined that the input from the throttle position sensor is lower than expected for the current engine operating conditions.
And is it normal to pull 3 codes at one time?
Any advice or help is appreciated.

The first two make me thing you have a bad or loose gas cap. The second one I'm not sure. It the TPS is bad it's fing expensive to replace. Typically the whole throttle body has to be replaced.
Often times having multiple codes like that means something like a bad ground. I'd probably look under the hood and make sure the TPS and all the vacuum lines look ok.

I have this on my 02 civic si right now. Took it to the dealer thought it was the gas cap turns out . It is either a vacuum control module (located on top of the gas tank) that costs like $450.00 to replace or it is a sensor on the throttle body and that costs like $250.00 to replace. They couldnt tell which cause when they put it on the machine it said everything was functioning as it was suposed to
I was told (by the honda dealer that checked it for me) it will not hurt the car to drive it that way and have been driveing it like that for about 3 months now and no problems. I will have to get it fixed before it can be inspected
Dont know what the other codes are or could be. But that is my experience with the P1457.

A P1457 IS NOT from a loose gas cap. It is properly defined as EVAP system leak, canister side. Properly diagnosing an EVAP system leak takes a skilled technician with the correct tools to troubleshoot the many components of the EVAP system.
The P0410 is is problem in the air pump's electrical circuit. It's possible the pump, pump relay or the wiring to the air pump has a fault somewhere. Air pump's have been known to overheat/melt., and ofter are damaged in front end collisions.
The P0122 is TPS low input.
All 3 systems (EVAP, TPS, and Air pump) share a reference voltage from the PCM. The 3 DTC's may be related, or they may just be a coincidence.

Any updates on what the fix for this was. My buddy's 00 s2k popped these recently. I'm trying to find out what it could be.
