Frequently Asked Questions

What is the most common reason for check engine light on a 1996 Toyota Tercel?

• Often a loose or improperly sealed gas cap triggers an emissions fault — an easy fix that clears stored codes.
• On older vehicles like the 1996 Toyota Tercel, aged oxygen sensors and catalytic efficiency issues are frequent causes.
• Minor vacuum leaks, worn spark plugs, or ignition components can also illuminate the light if left unaddressed.
• Prompt diagnosis at Nalley Toyota of Roswell prevents small issues from becoming costly repairs and protects emissions compliance.

What does it mean when the check engine light comes on in a 1996 Toyota Tercel?

• The light indicates the engine control unit detected a performance or emissions-related fault; severity ranges from trivial to serious.
• Common flagged systems include fuel trim, ignition/misfire, oxygen sensors, evaporative emissions, and catalytic performance.
• A steady light often means a non-urgent issue; a flashing light signals immediate attention is required to avoid damage.
• Our factory-trained technicians at Nalley Toyota of Roswell use OEM tools to read codes and recommend the correct repair path.

What is the first thing to check when the check engine light comes on?

• Check the gas cap: ensure it’s tightened until it clicks and the seal is intact — it’s a common and simple cause.
