Question about 1992 Toyota 4Runner
I don't see why it would not work.
The ecm would not have any connection with the drivetrain other than the engine.
The prom or chip should change the settings for timing and other factors.

SOURCE: code 52 1994 toyota 4runner
This code could mean knock sensor, knock sensor circuit, or ECU.When the knock sensor is replaced the wire should be replaced as well. If it's disconnected the knock control system is disabled which may cause engine pinging and the light will stay on.
There is probably a problem somewhere in the engine harness going to the ECM, even though the wires check good with ohm meter with this particular problem I have had to run a new wire from ECM to knock sensor if you replaced the short harness going from main harness to knock sensor under intake then you can try running new wire from short harness connector to ECM just temporarily splice wire at knock sensor connector and, connect a good piece of wire and run it inside of truck to computer and splice into wire at computer and see if code will clear, if so the cut wire at short connector and connect new wire with **** connector or solder and run it along factory harness as best as you can and do the same thing inside at computer. I am assuming you have checked all your connections, if not then do that before trying new wire. the knock sensor wore at computer is black wire on the smallest connector terminal no 5
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
