My "Check Engine" light came on this morning. At the local Auto Zone, they found the following codes: P0446 and P0773. But, they couldn't tell me what they mean, nor how to solve the problem.
The description for a Lexus (mine is a 1998 ES300, with 251k miles) is:
P0446
Definition: BBEVAP system vent control valve circuit.
Probable cause:
1) Open or short circuit condition
2) Poor electrical connection
3) Faulty vent control solenoid
P0773
Definition: BBShift solenoid "E" electrical malunction-SSV DSL.
Probable cause:
1) Open or short circuit condition
2) Poor electrical connection
3) Failed SSV DSL
About 50k miles ago, I realized I had waited far too long to flush my transmission fluid. At the time, EVERYONE said best thing was to not mess with it, as opening it could loosen metal shavings and cause a transmission to need to be replaced. I fear the time has come. I park on a steep driveway, and only recently learned to always apply the parking brake to reduce strain on transmission. Began doing so a week ago, and now this! Thanks for any help you can offer.

Failed leak detection pump. can this be caused by going through deep puddles?leak detection pump control circuit high. probable cause open or short circuit condition poor electrical connection.

From what I can tell, the 2 codes aren't related. The BBEVAP error can be as simple as changing the fuel cap (try this first) to a vacuum hose leak or a purge valve malfunction. As far as the transmission goes, first check your fluid and look at the color; if it's brown or gives off a burning smell, it really needs changing. It's true that the modern flushing system is bad for older transmissions but changing the fluid and filter through the transmission pan will be the only way to truly diagnose how bad the transmission damage is. Leaving old fluid in the transmission will only lead to it quitting on you sooner than replacing the fluid,filter etc. Hope this helps and best of luck!

Take it by an auto parts store like Auto Zone or O'Reilly Auto Parts and they can connect a reader to your car's computer and give you the codes. Write down the codes exactly as they say, and then find out what that code means for your model car on the internet.
According to my 2002 Toyota Tundra manual (and it may be different for your car) P0125 is as follows: Insufficient Coolant Temperature for Closed Loop Fuel Control
This would seem unrelated to your original problem.
HI. This will require you to have the engine CPU scanned for trouble code's. This can only be administered with the assistance of a diagnostic computer scan tool. You can purchase this tool at your local auto parts store, or you can just have the scan ran at your local auto zone parts store, free of charge. Once the diagnostic scan is administered, you will be able to isolate the issues that have caused the check engine light to illuminate.
This scan tool will display a print out code and the location of the issue, on the engine, as well. There are Many issues that will cause the engine light to illuminate, but the most common cause will be a failed monitoring sensor, or sensor harness failure(separated power wire, or ground).
Once you have the codes, kindly return to the site, and post them here. We will be able to assist with more accuracy, once the codes are posted.
SOUNDS LIKE A CATALYTIC CONVERTER.... BUT GO TO YOUR LOCAL AUTO ZONE OR YOUR PERSONAL MECHANIC AND HAVE HIM DO A OBD SCAN IT WOULD TELL YOU ALL THE DEALER FAULT CODES.... AUTO ZONE IS FREE LOCAL MECHANIC AT LEAST $250 FOR A 10 MINUTE PROCESS
have you checked the oil it may be low on oil or you may have a bad cps(cam posistion sensor) so it is not exactly firing correctly you can go to auto zone and they will check the codes for free even if you dont see the check engine light on there will always be some type of codes stored. even codes that say no codes found. this will atleast give you a starting point.
For some reason, the ESC system "thinks" the drive wheels are slipping and it is trying to prevent the tires from spinning.
Take the car to your local Auto Zone and ask them to scan the car for trouble codes, they will do the scan for free. Write the codes down and respond back to this post and we can start to diagnose the problem.
Good luck and let me know.
Regards,
You need a code scanner hooked up to it to find out why the light is on.
If there is an advanced auto or an autozone near you, go there and tell them the engine light is on, and you need a code retrieved. They don't charge for this, where other places do. Tales about a minute.
P1410 - Fuel Tank Pressure System P0441 - Evaporative Emission Control System Incorrect Purge Flow P0773 - Shift Solenoid Electrical P0446 - EVAP Vent Solenoid Valve Control System
Ok, above are the codes listed on your description and there respective definitions. the P0441 and the P0446, basically run parallel and they mean the same thing. Its concerning the disposal of fuel fume waste that is burned in the EVAP canister during the EVAP process. the EVAP vent solenoid valve will have to be replaced.
The P1410 can be resolved be replacing the fuel pressure regulator which is part of the fuel pump assembly. I would also make sure the gas cap is correctly screwed on and its tight and mot lose.
The P0773 is quite different than the others. this concerns the solenoid that is located in the transmission pan. the scan has detected a malfunctioning solenoid that may ****** the shifting cycle of your transmission.
The EVAP situation will fail the emission's test if not fixed but, this shift solenoid issue, although not an emission's issue, should be check and fix soon.
I looked up the codes you posted.
P0420 is showing a bad oxygen sensor on bank #1, the one down by the catalytic converter.
P0773 is an electrical problem with the shift solenoid E.
A bad oxygen sensor would cause lower fuel milage.
