Assuming you've done the obvious and simple step of pulling the code for free at Autozone or such:

Pull the EFI relay (in box next to batttery, look at the label inside lid) for at least a minute and a half.

If there's still something wrong (you wouldn't shut it off unless you thought you'd fixed a problem, right?), it'll come back on.

Then fix what's wrong.

Not fixing the underlying problem is just asking for cascading failures.

i want to know too.... can someone help??

He can't reset his '94 that way. His is OBD-II & requires a scanner to reset it.
Take it to autozone & tell them it's a 1996.


1993, you pull your EFI fuse a second & replace it. TCCU (ECU) Codes are reset.

Well, the thing turned off, whether by my hand or not. I was fooling around with the battery and lots of nearby stuff, so who knows. Fine wth me if I never need to know again.

It was moot anyway, O2 sensor was shot. What with the water pump popped as well, the past week has not been happy motoring.

But all is well now, I have my Lex and the mechanic has Christmas covered.

Pheonix

Hahahahahaha. Atleast it's cheaper than a car payment!

After 210,000 of trouble free driving....my check engine light went off today the o/d (overdrive) light is flashing too
I went to Kragen and ask them if they could check the code, and they said they couldn't do it. I thought you can get the service for free somewhere?!?!?
Also, when I'm on the freeway, my rpm's are higher than normal on a flat roadway going at 70 mph, @ 3000 rpm X_X

***also, a small question unrelated to the first, since my car is 210,000 miles, and the timing belt was replaced at 95,000 miles, does that mean I'm overdue for a belt change?!?!?!?!

Lexucan

On 1995 & prior models, replace T-belt at 60,000 mile intervals. On 1996 & later models replace every 90,000 miles or 72 months under normal service, or every 60,000 miles in severe service.

Pheonix

They updated all the old ones to the 90,000 mile interval & change the water pump with the belt. Inspect the tensioner, idlers, etc. They normally last 180,000-270,000 miles. (Well really more the 250,000m+ range) before the uerathane/plastic they're bonded with finally just starts giving up the ghost, or atleast becomes old enouh where you'd probably want to change them, just so you didn't have to inspect them often to "make sure".





tuan92129 - the actualy TCCU (Toyota Computer Control Unit) which handles all engine & transmission logic is OBD-II.
The rest of the vehicle is OBD-I, which is why you're OBD-II, but the older diagnostic ports are still on the car.
You're engine & Transmission codes are read only by an OBD-II scanner. Kragen is just stupid because like autozone. They think a vehicle has to be 1996, or newer to be scanned. Just tell them it's a damned 1996 and be done with it! LoL! Your rpm's are higher than normal because youa re in limp-mode and the over-drive gear is locked out.
STOP DRIVING THE CAR!!!!!!! (Not to be mean or anything!)





Get the codes scanned. Lie if they ask the year & let's go over the codes & get you resolved & fully functional before something really bad happens.

Anyways, I lied and told them it was a 96...
the code is P0773
Shift Solenoid E circuit Electrical

(I don't get the 'E circuit' part....is it an electrical problem or a transmission problem?
-My o/d (overdrive) light stopped flashing today...why?

Anyways, after i checked the code, I told autozone that my car is a 95, and that the 96 rule is not always true..and they told me that my car must be a late model 95 that came with obd II

Pheonix

You're mis-reading. It's shift solenoid E - circuit malfunction. The solenoid is dead, or the wiring for it.

Intermittant fault. Test the wiring, replace the solenoid.

I like OEM Toyota solenoids, or NAPA solenoids.


In all honesty... I think the NAPA solenoids are alot better engineered when I replaced my main 2 shift solenoids. They appear to be able to let more fluid through, along with being machined out of bigger billet stock, with biger hold down plates <where applicable> and better wiring / harnesses.

Also, a couple times, when I'm stopped at a traffic light, the speedometer just goes crazy...0-130-50-39-5-87-0-,.....
Should the speed sensor be replaced too, or is this a circuit board problem? (BTW my odometer starts adding miles when this happens X_X)

Hopefully, I'll have the car to drive before school starts
Thanks.
