Question about 2001 Toyota Corolla

1 Answer

2003 Highlander (AWD V6)

My check engine light is on and I found my gas cap loose. I have secured it and wondered when/if the check engine lite will got off if that was the problem. I have been driving the car for 3 days and the lite is still on. Will it take several complete drive cycles or will the code have to be erased by a scanner or other means ? Thanks for any help, John K

    Thank you for your help. You are absolutely correct: the loose gas cap did trigger the check engine light. After driving for another couple of days (probably 2-3 complete driving cycles) the light did go out.

The gas cap turned the light on ( I assume you knew that), go to kragen auto and ask them to run a OBD 2 code test, when they get the code ask if they will clear it for you with the scan tool, this is free, other parts stores do this as well for free. If you want to wait the light will clear after a complete drive cycle, this can take up to week depending on what kind of useage the car gets.

Can you bolt a 2006 3.6 v6 to the transmission of a 2003 which has a 3.4 v6?

I'm not certain if it would physically bolt in, but it would be a nightmare to get the electronics working properly. I found that the 3.4L isn't a bad engine, aside from intake gasket leaks. There is an updated intake gasket set available that seems to be working great.

I have a 2003 Toyota Avalon. My toyota problem is the check engine light that came on.

Hello. Welcome to FixYa. Please allow me to assist you. The Check Engine light comes on for many, many different reasons. The most common reason is the gas cap being loose. I would check the cap for being loose. If it is loose, drive the car for 10-15 miles to see if the light goes out. If the cap is not loose, you should go and take the car to someplace that can scan the car's computer to get the codes, the reason for the light being on. Autozone stores do this for free. Get us the codes, and then we can isolate your problem better.

Check engine light on codes p0442 p0456 p0513

P0442 and P0456 are both evaporative emission error codes due to a small leak. The most common cause is a leaking gas cap or hose leak on that system. I did not list a code for your 0513. I am sending you a little information about your problem.. Best of Luck to you..

Check engine light is on with trouble codes P0442 and P0456. The codes are evaporative system small leak codes.
1. Verify that the gas cap is a factory Toyota gas cap and visually inspect that all hoses and lines are tight and connected.

2. Locate the canister closed solenoid and the vacuum switching valve on the canister. Manually ground them and verify that they operate and function. The canister closed solenoid is normally open and should close when grounded. The vacuum switching valve on the canister is normally closed and needs to open when grounded.

3. Verify that the hoses are not loose or pulled off the canister closed valve on the air cleaner housing. This has been a common problem on some models.

4. If no problem is found, the next step is to ground the canister closed solenoid and the vacuum switching valve under the vehicle and simulate an evaporative test and verify that the system holds a vacuum and functions normally. When the solenoids are grounded, back probe the Blue/Black (L/B) wire on the pressure sensor, and with no vacuum or pressure, the voltage should read around 3.3 volts. Start up the vehicle and turn on the purge vacuum switching valve and use engine vacuum to draw down the system to around 2 volts on the pressure sensor. If the voltage does not increase rapidly, there is no problem. If the voltage increases quickly, look for the leak in the evaporative system. Potential Causes: Canister Closed Valve
Disconnected Canister Closed Valve (CCV) Hose
Gas Cap
Vacuum Switching Valve - For the pressure sensor.

if the air filter was recently inspected or changed, look for the vacuum hose to be disconnected from the valve located on the air filter cover. another source may be the gas cap either loose or with the tether strap caught under it preventing a proper seal

If you live near an AutoZone they used to offer free check engine light diagnostics.
See what code they can retreive from the computer with their device and check it against the list of codes. It may not just be a missing Gas cap code. There are hundreds of codes computers can return.

Best Wishes.

How to clear codes/check engine lite

under the hood on the left side is a fuse panel, if there is a single EFI fuse, remove it for 30 seconds or so, if there is more than 1 efi fuse remove them both along with the fuse marked e.t.c.s. leave them out for 1 minute or so and that will erase the code and reset the light. make sure the key is switched off before removing fuses
