How do you test an ignition coil?
How to test an ignition coil This testing procedure is valid for just about any automotive coil. Using an ohmmeter, check the resistance between the side terminals of the coil. Do this with all of the wires to the coil disconnected. You should see 0.75 to 0.81 ohm of resistance. Then check the resistance between either side terminal and the center high tension terminal. The reading should be 10,000 to 11,000 ohms. Any significant deviation from these numbers would indicate that the coil could...

What are the OBD-II pins?
Honda Man's Since we don't know what make, model or year your car is, this is a difficult question. If it is in fact OBD II, the connector should be located under the driver's side dash. In order to find your codes, you don't need to plug into the obd2 port. On the bottom right side of the diagnostic port, there should be two pins rather close together. My recommendation is to go to Auto Zone. Some of their stores actually have...

How do you rewire a 1986 Toyota Celica derby car to bypass the computer and other irrelevant units?
Computer? Yeah, who needs it. It's only the heart and soul of your entire car. You can ditch the computer if you remove the entire intake and put on a carburetor, remove all the emission control components (remember to plug all the holes or you'll lose engine vacuum and that's BAD) and fabricate and install a manual fuel pump. Then replace the entire ignition system with an old "points" system that you'll have to replace every 3000 miles. (oh yeah, you'll have...

Asked in Car Computers and Sensors, Toyota Corolla
How do you remove oxygen sensor from 1990 Toyota Celica ST?
First off use a spray lubricant very liberally on the threaded area of the sensor. (I recommend PB Blaster. It is a miracle in a can!) Secondly, cut the lead wire close to the sensor so you can use a socket on it. (preferably a 6 point to reduce the risk of rounding off the soft brass hex. Use 1/2" drive for leverage). when installing the new one use a crescent wrench. Do not over-tighten. Mike ...

To change it usually requires removing a bolt and pulling out the sensor. Rwd vehicles either have the sensor in the transmission, transfer case(4x4) or in the rear differential. The replacement procedure is similar. ...

How do you change an oxygen sensor on a 1994 Honda Accord EX?
If the sensor has never been changed it may need to be heated with a torch in order to loosen it up if it will not loosen right away with the socket. Don't use force until it is heated slightly which will contract the metal and make removal easier before stripping or breaking it necessitating drastic measures. On a 1994 Accord it is located on the exhaust system next to the catalytic converter. You unplug it and then loosen it with...
