Low idle

• Throttle position sensor (TPS)-The TPS control the amount of air entering the throttle body at idle essentially. To adjust this, just go here…

To check if the TPS is functioning, disconnect the harness connector and attach the probes of a voltmeter to the REF terminal (+) and the GND terminal (-)(Inner and Outer will cover both), and with the ignition in the “on” position it should read around 5.0 volts. If this is not the case then there is either an open circuit to the PCM or a defective PCM. Next check the TPS signal voltage, take the keys out, and reconnect the harness to the TPS, and back probe the electrical connecter SIG terminal (+) and GND terminal (-) using pins. Be careful not to damage the wiring harness. With the ignition key in the “on” position and the throttle fully closed. Gradually open the throttle valve and observe the TPS signal voltage. The reading should be between 0.5 to 1.0 volts, slowly move the throttle valve and see if there is a change in the voltage values as the sensor travels from idle to full throttle. The voltage should increase smoothly to approximately 3.5 to 5.0 volts. 1993 four cylinder models TPS is a permanent part of the TB, and if out of range the entire throttle body must be replaced.



Leaking break fluid

• Master Cylinder-This is the container for the brake fluid, there are 3 lines running from it. One to the front left, one to the front right, and one to the rear. Check the front first, they will be harder but it seems more logical that one of them would break first. Inspect the unit and ensure that there are no cracks or any leaking fluid.
• Calipers and or any rubber fittings- To locate the leak, take the wheels off and look at all of the rubber hoses and connections, and the wheel well. Do this while someone is pressing the brakes to make it easier if you choose. The leak should be visible.
