1995 Toyota Corolla Timing Specs
Correct ignition timing specifications are crucial for engine performance. Timing affects many variables, including fuel economy and engine longevity. Corolla is one of the most popular compact cars, introduced in 1966 by Japanese automaker Toyota. Its engineers have determined precise timing specifications so that you can maximize benefits and use of your Corolla as much as possible.
Adjusting Timing
The base timing on the 1995 Toyota Corolla is preset when the company manufactures the engine, and no adjustment is possible. The powertrain control module (PCM) manages timing advance and retard, along with with ignition control (IC) and knock sensor (KS) systems.
Base Timing Specification
The best time at which the air-fuel mixture should be fully burned on the 1995 Corolla is 10 degrees before top dead center (BTDC) with the maximum allowable difference of +2 degrees both for the 1.6 liter and the 1.8 liter engine. The engine should run at about 700 RPM.
Notes
Allow the engine to warm up before measuring timing. Also, reaching maximum RPM is not allowed during the ignition timing check. Cooling fan and vacuum advance should be turned off while you are adjusting the ignition timing.
