Could anyone please tell me if there is a way to interpret toyota engine
light codes without any special tools.
I know K-Cars, and some other vehicles, have a way of interpreting
problem codes by turning the ignition key a number of times and counting
light flashes.
Is there a similar process I can use to determine the reason for the
"check engine light" coming on?
I have a 1985 4runner with a 22RE engine if this helps.
Thanks in advance.
Dave
What year is your truck, is it obd or obd 2?

I’m not sure what you mean. It was made in July 85. Does this help, or
is there something in the VIN?

OK…here ya go.
Short the terminals of the check engine connector located near the
ignition coil. (This is the more or less famous, much discussed, yellow
plug that on my ’85 22RE 4×4 p/u is shoved into a rubber receptacle
holder doohickey on the driver’s side fender.) I use a bent paper clip
for the shorting wire.
Turn the ignition switch to ON – don’t start the engine.
Read the code as indicated by the number of flashes of the "Check
Engine" warning light.
For a normal op code, you should have a blink about once every 5
seconds. This sez nothing is wrong.
If you have a malfunction, the light will blink a number of times equal
to the malfunction code every 5 seconds.
There are 12 codes:
1 blinky – Normal
2 blinky – Air flow meter signal
3 blinky – Ignition signal
4 blinky – Water thermo sensor signal
5 blinky – Ox sensor signal
6 blinky – RPM signal
7 blinky – Throttle position sensor signal
8 blinky – Intake air thermo sensor signal
9 blinky – (there is no 9)
10 blinky – Starter signal
11 blinky – Switch signal
12 blinky – Knock control sensor signal
13 blinky – Knock control CPU (ECU)
That’s it…..straight out of the original ’85 manual. Please don’t
ask me what all these malfunctions mean or how to fix them. The manual
goes into massive detail on all this stuff and I still can’t figure
most of it out. But, the code(s) will send you off on a direction that
might help.
Good luck…..

BTW, you need to disconnect your battery or pull your EFI 15A fuse out
for about 30 seconds or more with the ignition switch off. This fuse
is up under the left side of the dash – in the box.

WOW!! It major brainfart time! Forgot to say that the above procedure
is used to clear the code(s) after you’re all through getting the
skinny.

Yes, by your air clear is a round yellow connector, jump these 2 wires,
keep your foot off the throttle. It will blink out the codes.
