Obd code 401 and 402 for 1999 toyota camry

I have already replaced it. I also replaced the modulator as well as the valve, I replaced everything so that Im sure that everything was working even though it cost me a lot. After everything was changed the car runs better, but once in a while it stutters. What else needs to be checked?

There are 3 types of mechanics...one who is willing to help and solved the problem right away...very rare, second is fixed the problem, but will loosen other connections so the car will be returned for repairs again. Based on experienced, the mechanic who last worked at my sisters car loosen the connection of his 1999 Toyota Camry EGR port to the engine and she is getting DTC 401, and the last is... guessing games for non-experienced mechanics. My sister is a victim being an unsuspecting customer who doesn't know anything about cars. The world needs money...Suggest don't dress as if you are an executive who earns lots of money and their impression to you is that money is not an object, get referral to friends who had car problems and was fixed without going around the bush. Nowadays, you don't know who are good and bad mechanics.

P0402 1997 Toyota Camry 4 cyclinder 4 door, encountered P0402 has 3 months already. The car is drivable. What is the solution? Could replacement of a vsv value resolve this issue? Which part can I buy


Hi,
That is the code for Exhaust Gas Recirculation Flow (EGR) Excessive Detected

Go to the site and review what causes and can be checked to fix it.

I'd start w/cleaning the EGR valve - free fix - and then consider replacing the part. I'd look for USED parts @ a local Salvage/Wrecking yard vs. buying new, due the cost and the fact that this is an older car.

1999 toyota camry 4 cyl check engine light on code reader said egr valve


A common problem for egr failures are the modulator valves, the valve is attached directly to the egr valve, it's a round plastic housing with three vacuum lines on it, try replacing this valve.

Please GeoffW1 this are the fualt code diagnose from my toyota camry 1999 model v6 engine FAULT NUMBERS- 1.( p0110 ) 2.( p0135) 3.(p0450) 4.( p1410) 5.(P1411) please i need their locations and...


Sorry, I never noticed this post, for some reason I did not get an email from Fixya. If it is not too late..........
p0110 is the Intake Air Temp sensor or its wiring connector at fault. This is located at the side of the air cleaner housing.
p0135 is a fault in the No 1 oxygen sensor in bank 1, or its wiring connector. This thing is located in the exhaust manifold under the sheet metal shield at the front of the engine
p0450 is an evaporative emission system pressure sensor fault. Many people recommend replacing the fuel filler cap gasket before going further with this one

http://repairpal.com/OBD-II-Code-P0450



p1410 and p1411 indicate an EGR valve malfunction, and it may be enough to simply clean and check it, located on the engine next to the firewall. Also check the vacuum modulator and Vacuum Switch Valve, as shown here p46, 146, 152, 190

Every now and then the car wants to stall but it does not


You have verified the EGR valve will operate when vacuum is applied so the valve and chambers are good..correct? If thats the case, then
your issue here is the VSV (vaccum switching vavle), these intermittently get stuck. Follow the vaccum lines down behund the intake, you will find the vsv located on the back side of the block just above where the drive axle mounts to the block.
Replace this VSV and the modulator valve at the same time, they tend to fail togather.
Good luck, i hope this helps...please rate me a fixya

P1410 Code on a 2000 Toyota Camry


P1410 EGR Valve Position Sensor Circuit Malfunction
You may have to replace the sensor. If you get a chilton manual at an autoparts store, it will show you how to test the sensor with some test values in the book. The book should run about $20

OBD code 0401 (1997 Toyota Camry 4 cyl)


There is a VSV (vacuum switching valve) , usually mounted on the back side of engine block, under the intake manifold, as well as the map sensor, that can also cause that code if one or the other is faulty. It takes some pretty detailed troubleshooting to confirm this in some cases, so if that's not in your line of work, you may have to have it properly diagnosed, or take a 50/50 shot at which one first.
