I took my car to Autozone for a code check. My car reported the code that there is a PCV vacuum leak. I replaced both the PCV valve and later the PCV tube on my 2002 Honda Civic.

Will the indictator eventually turn off by itself after a few trips, or do I need an OBD II scanner to clear it?

Thanks in advance.

You can either clear it with a scanner or disconnect the negative battery cable for a minute. Autozone can clear it for you.

No, the cars computer produces fault code numbers.
Autozone prints a shopping list to get you to buy a lot of parts of dubious quality....most of which only generates revenue for the store and clerk.


What fault code number did your car have?

You could actually disconnect the battery to erase the code.
Make sure you know the code to get the radio unlocked before you attempt this though.

If you didn't solve the problem, the code will return.

What code number?

I didn't see OP post ANY code number.

i would get the actual code before putting too much effort into it. i have actually had a girl at my local store pretend to scan my car. i've had others try to sell my TPS sensors because it would show 14% and they're not bright enough to know that is tared out like a scale. you really just need to use them for the code and nothing else. you may have no vacuum leak and they are having a manager inspired PCV selling contest today. usually the contests are who can sell the most injector cleaner or had cleaner, but sometimes they get bored. there is an oil change place called "the duke of oil" by my house and every day the employee that sells the most pcv valves gets an extra $5

it could also just be a fluke. i'd clear the code and see if it returns.

Thanks for the replies.

My car got two codes:

P0505 Idle Speed Control System. (I removed the throttle body and IAC valve--cleaned both first with two cans of CRC throttle body cleaner and then Super Clean foam. The later was much more effective in breaking up the carbon deposits especially in the IAC. I used a small wire brush, Q-tips, and pipe tobacco cleaner--a small, flexible wire with cloth bristles. As the can says, I made sure not to let it dry on the items and also "rinsed" with a wet towel and then dried them..) I reinstalled both and did the idle relearn procedure. Driving was "choppy" at first, but it improved as I drove more.

I also got code P1505 PCV Air Leakage. I replaced both the PCV valve and the PCV tube (which I got from Hondaautoparts.con. The site has detailed diagrams.) I replaced the PCV valve a few years ago when my engine would die at red lights. It then ran fine. The valve I removed passed "the shake test." Since it's inexpensive, I bought a new one. The old PCV tube seemed hard, and I couldn't see or feel any tears.

Do I need a scanner to clear both codes? If it's not the PCV valve and/or the PCV tube, then what else would trigger "P1505 PCV Air Leakage"?

Thanks again.

P1505 can probably be caused by P0505. Figure out P0505 and the P1505 will probably stay gone.
SOMETHING is causing it to idle in a way the computer isn't able to fully control the idle speed.

The way I read my info, I think the P0505 and P1505 can both be caused by a vacuum leak. That includes the usual stuff everyone thinks of first (also check brake booster and EVAP purge valve for leakage), and/or internal leakage such as an IAC valve that is stuck open.

UPDATE: The light went away on its own, suggesting I properly cleaned the throttle body and the IAC valve and reinstalled them, and a new PCV tube solved the leakage code issue.

Anyway, thanks for your input and suggestions.
