Hello, and welcome to FixYa.
Please allow me to provide assistance to you.

The P-0401 code indicates an issue with the EGR valve. Normally, the most common problem is that the EGR valve sticks slightly, in the open position. To correct this condition, and to eliminate a potential for the engine to start stalling, when the valve finally sticks fully open, is to replace the EGR valve, the EGR transducer, and the EGR vacuum switching valve. This is a very common problem, and easy to rectify.

Thanks for choosing FixYa for assistance.
The graciousness of a FixYa rating for my input would be greatly appreciated.
Thanks in advance.

1998 toyota camery le engine light on misses when i give it gas

The engine light is on because the car is telling you that something is wrong. It is putting out codes and you need a diagnostic tool to check for the solution.

I read the check engin light on my 1993 toyota camry le and it gave me to codes: DTC:14 and DTC:26... What could be wrong with my car?

Code 14: Igniter circuit, probably a faulty igniter
Code 26: Fuel mixture too rich, possibly a faulty coolant temperature sensor, or faulty oxygen sensor

Hi there,

Your ABS light will remain illuminated if your vehicle's PCM has detected an abnormality or fault condition within your ABS circuit.

You will need to have your local Toyota dealership (or approved agent) scan your vehicle computer for the diagnostic trouble code (DTC). The codes will identify the suspected circuit/component.

Chances are, one of your wheel sensors may be either dirty, or has failed. There could also be an issue with any of the brake components, or even the ABS computer itself.

Check eng light trouble code PO420 bank 1 on toyota camry 2002 le replaced top oxygen sensor reset codes and check eng. light came back on.

More often than not the Cat is bad. Replacing the sensors is the easiest move. Reasons for the cat to go bad will be related to something else wrong with the fuel management and emissions systems in the car, improper sealants or chemicals used on prior repairs causing damage to the cat

92 toyota camry e electrical question

I had the SAME problem with my 1992 Camry LE...except without the water..First, check the back up lamp fuse (there is more than one circuit on that fuse, not sure which). The water would have likely shorted out the circuit. First check for power at the reverse bulb while the car is in reverse (You can do this with the car off) If there is power, check the ground wire, if it is bad...if you splice the ground wire before the connector and run a new wire to a ground in the trunk, then it should work..thats what was wrong with mine..hope this helps

Interior little car stays on

The bulbs have to be correct also. The third brake light is easy to get the wrong bulb. Also the light module itself could be fauty. It is in the trunk. You could also ignore the light.
