most commonly the fuel presser regulator on the 22r and sometimes even the 3.0
six cyl motor. many things will make the check engine light come on, i would buy denso only from ebay for around 47 dollars and try changing the o2 sensor in the exhaust first. ez change takes about 15 minutes and getting your back dirty , with a common 17 mm wrench,, do you have a 22 re or three point o

Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. We just found out that the check engine light on our 1993 Toyota Pickup is due to a bad "knock sensor".
