1.6L or 1.8L? engine.there are 3 engines,
1.6L with one injector and one with 4 and the 1.8L with 4.
and the ecu is different on each.

tell which terminals were jumped. and which lamp flashed?
Corolla - jump DLC terminals TE1 and E1 with a short lead 1

which transaxle.?
A131, A240i, a241h, or A245e, (the e trans is tcm shifted)
The 7AFE engine has the TCM and ECU in same box.
the 1.6L single injector engine runs a pure hydraulic trans.(no TCM)
TCM's engine/trans setups.
the 4speed, has 3 ranges switches, and 3 solenoids. and speed sensors., the MPI engine ecu shifts the transmission the TBI engine does not. MPI has 4 injectors, this your car?

if the OD flashes driving, this means TCM sees errors.
can be bad sensor inputs to the TCM
or bad shifter switch, (really they are sensors too, status switches)
and the TCM can see bad speed sensors.
the TCM can also flash if the solenoids are dead. or transmission slips. (nut shell answers)
IF it skips gears, the TCM may be in limphome, they do that on errors. to protect the transmission for damage.


first, off , prizm is just a toy corolla and those are really corolla

best page on car., but i cant find your codes? are you sure you counted correclty? 26 is too rich running. (fuel ratio) 36 I can not find anywhere, (stumped me)

post vin on car and we can look up what's under the hood.
put xxxx and end of VIN. for privacy.

Check the fuel filter. It should be changed at regular intervals. Otherwise it can get clogged.

Sounds like a bad blower motor resistor. Since high speed bypasses the resistor and the lower speeds use the resistor and don't work, the resistor is the most logical answer. It is usually mounted near the blower motor under the passenger side of the dash.

replace inlet manifold gasket,?

what is the problem?
is your car overheating?

there is a program that i use on the internet that has all the info you need including tsb's and wiring diagrams. type eautorepair.com then scroll down and you will see diy. the program costs 12 dollars but has priceless info. you will find everything you need there, and if you have any trouble they have people that can help standing by. i have used them on several occasions and their diagrams are profesional quality.

Yes a harmanic balancer from tha corolla is the same thing. I had to do the same thing with my 95 geo. It works out to be a lot cheaper buying for a toyota than a geo.

I had the same exact symptom (02 Prizm LSI)..Order yourself a Blower Motor Resistor (I clicked on it---scroll up on this same screen that you are reading--- AC Delco part, $25.79). When the part arrives, look at it, and then look behind and to the left of your glove box door, YOU WILL SEE IT RIGHT AWAY. 2 screws, takes about 10 minutes to change. Its been nice to get all 4 speeds back! Good luck.

You didnt specify which transmission your car has,the 3 speed,model A131L,or the 4 speed A245E.Both transmissions basically have the same elements applied internally when acquiring Reverse gear.Forward clutch off,Direct clutch and Low Reverse clutch applied.The major difference between the two available transmissions for your car is,the 3 speed trans is totally hydraulic,no electronic controls,while the 4 speed trans is totally electronic control.Check the fluid level first,regardless of trans model.If your car has the 3 speed trans,it is likely an internal trans problem.Same thing for the 4 speed model,with the exception that the problem could be the electronic solenoids malfunctioning.The solenoids should be deemed defective or good,before a determination is made.
