Hello guys i just a question. i recently had a P200A (Manifold Failure) and i was wondering what it could be? i recently installed some used Stillen Gen 3 intakes on my g37 sedan and since then it has been giving me issues. Also overtime i accelerate about 2500-4000k RPM i hear a hiss in the intakes ( air pulling through intakes kinda sound). Also another question i recently installed new rims (went from 17 inch to 19 inch rims) and i had my old original sensors swapped and put on the new rims and my (i) (TPMS Sensor Light) is still on? anyone have any suggestions as of what i should do? Thank you guys!!

 

Anyone guys? Thanks

 

possible vacuum leak or pin hole leak in the intake pipes due to rubbing. check all connection fittings and clamps and overall condition of intake pipes. as for your tpms you most likely need to normalize and program it again. worst case scenario is the tpms sensor was damaged during removal and reinstallation so you may need to replace it.

 

Likely a leak after MAF sensor. If you find the source of that hiss you will likely find your leak.

 

For future reference and to make the forum a better place for everyone, give it a bit more than 10 hours before you bump your own thread asking for help again. Especially when your first post is late at night.

 

Thanks a lot I will look into it and see the issue hopefully I can resolve it

 

Thanks man will check it out

 

My badd lol

 

and can you elaborate on the vacuum leak or pin hole leak ? Kinda lost. Thanks

 

The G37 does not have a "P200A" code, or a "P0200" code.
Scan the car again, post the code and I will walk you though next steps.

As for the TPMS light, try this:

 

No way! The TPMS light blinks with timing to indicate which tire is at fault? Are you kidding me?

All these years I've been b1tching about this, and turns out the actual problem is that I'm an idiot. OMG.

Is that in the FSM or the OM somewhere?

 

WT-21, in the FSM.

I wanted to test it before posting, but I don't have any TPMS issues.

 

omg, is it really that hard to understand what i posted as advice prior? vacuum leak is any unregulated air that is entering into the engine from any connections points or hoses and lines. i specifically stated look for "possible" pin hole leak on your intake pipes because many times when people install intake pipes they leave it unsecured and when it rubs on other components in the engine bay it can create a "pin hole" leak which is a type of vacuum leak but is the result of damage. the hole created as a result of the damage is usually a small pin sized hole.

 

It says the blinking pattern identifies an inactive TPMS not a low pressure tyre.

 

TPMS:
Your best bet is to take it to a tire shop or dealer where they can see if each TPMS is transmitting and ensure they are paired to the TPMS system. I assume the TPMS light was off before the rim swap.

Post the engine code when you can.
