I have a 1994 Toyota 4Runner with a V6 and the check engine light came on i jumped the terminals and code 14 and 26 came up. what does the codes mean?

There is probably a way to access codes by using a jumper and causing the engine checklight or an integral led to flash in groups. I can't say which pin or pins need jumping.

I suggest you ask the question of google and click on the youtube video.

PO125 INSUFFICIENT COOLANT TEMPERATURE FOR CLOSED LOOP CONDITIONS.POSSIBLE CAUSES - LOW COOLANT LEVEL - STUCK OPEN THERMOSTAT OR FAULTY ENGINE COOLANT TEMPERATURE SENSOR. DID NOT SEE CODE P1139.

take it to advanced auto parts. they will hook a computer up to your car for free and tell you the codes. you dont need to be jumping anything

The check connector is located near the No. 2 relay box. Short terminals T and E1 of the check connector. (jump together)
2. Turn the ignition ON. do not start engine.
3. Read codes by the number of flashes of the "CHECK ENGINE" WARNING LIGHT.
4. System normal: blink every 0.25 seconds.
5. Malfuction Code: light will blink a number of times equal to the malfuction code.Between first digit and second digit, 1.5 sec
Between code and code 2.5 sec, between all malfuction codes 4.5 sec
6. The diagnostics code series will be repeated as long as the connector terminals T and E1 are jumped.
7. Codes are 2 digit numbers

Check engine light. You will need a OBD II reader to retrieve the code.
Please let me know what you found.

With any trouble codes you can not get away with not trouble shooting to find out were the problem is at.

that code is for rpm signal and possible causes are the distributor wire harness from dis. to ecu (engine computer) or ecm itself! do you have rpm tach working on the dash? if so it might have seen the fault for a few seconds and set the code if you don't have rmp tach then you need to diagnois the cuase by testing the signal out of the dis. then down the line! if you have any more question please ask. good luck

For a V6 # Liter engine, you will use a galon and almost half (that is about 6 Liters of oil). I use a Toyota camry V6 3 Liter engine that shares the same engine with the Toyota 4Runner.

It has a trouble code, you need to have it scanned. The light will flash the trouble codes if you jump terminals E1 and TE1 in the diagnostic plug.
