My 86 Toyota truck with 22RE engine does not have the diagnostic box beside the fuse box. The "Engine" light on the dash has been coming on briefly. Any guidance on how to read codes?

I have two 1997 Tacomas, one being a parts truck. The LX has an OBD2 port under the left side of dash by driver's leg. Pretty standard location and easy to connect to. The base model has a 17 pin OBD1 port in an easy to see location in the engine compartment and I was resigned to the paper clip trick. Then I stumbled upon a video where the mechanic told of a sneaky manufacturer / dealer racket during the late '90's and early 2000's. In 1996, the government required all cars to be equiped with the a standard OBD2 connector. This would take money of the dealerships as propriatary connectors were SOP for quite some time and only dealers had the correct code reader plug. Manufactures actually complied with the law, but they often put the propriatary port in an obvious location and a secondary OBD2 port hidden somewhere else. I found my "hidden" OBD2 port neatly tucked away under the right side of the dash mounted vertically. Easy to connect to once you knew where it was. However, some were more cleverly hidden as the mechanic in the video had to removed a small tilt out glove box type compartment to expose a fuse panel with the OBD2 port mounted above it. Sneaky. Just thought I share should anyone else have a similar problem.

I have codes 13 and 14. Looked up and 13 is no ECM signal over 1000rpm and 14 is no igniter signal to ECM. Does the ECM receive its signal from the igniter unit for both codes?

How would you replace this diagnose port. Mine is not working. Something pushed out on the main te1

I have a 1991 Toyota T-100 6 cylinder 3VZ engine. The engine shakes at idle speeds, especially when stopped at red light (in Drive pushing the brakes). I have an Actron 9680 but it only reads 1996 and up models. Can someone help me out by giving me info on a diagnostic which could read a 1991 Toyota T-100 ? Thanks. I changed spark plugs, distributor cap and rotor, air filter, and removed and cleaned throttle assembly. Also install new motor mounts. It improved a lot but it still shakes. Idle RPM reads approx 650, and it should be 800. I appreciate any helping info anyone has. Thanks.

If the overdrive light is flashing do you follow this same procedure?

So the hesitation was due to a bad speed sensor??? I’m having same issue
