My 2003 4 runner is recommended for 32psi. Check the drivers door jam. On it you will most likely find a sticker telling you the correct tire pressure.
Check your maintenance manual. It's in there.

Type your answer here... Hello how do you reset the check engine light on a 2003 Toyota 4runner. Thanks
Because the ECU has detected a problem with the emissions system.
Same place you check the fluid level.
Check the brake light bulbs, one of them may not be installed correctly.
The engine is building up back pressure which forces oil into the breather. Check the air inlet hose and see if it is pulling a vacuum. If not you will need to clean it and replace the PCV valve.

Problem with emission control system have vehicle scanned to determine the problem
Check the door panel on driver side. It has a plate with the information specific for that year and model.
