Check Engine Light

Cars have lots of electronic indicators and warning lights to alert us of problems going on with the vehicle. The “Check Engine” light is probably the most concerning one for us to see. It tells us that something’s wrong, but it doesn’t provide any more specific information as to what! The check engine light is designed to alert us to any potential problems in the “Powertrain” of our car, meaning the Engine, Transmission or the All-Wheel-Drive system.

If your check engine light is flashing, this could indicate a serious problem and could cause serious damage if ignored. Stop driving the car and give us a call.

When you bring your car to Martin’s Auto Service, we will do more than just read and clear engine codes, we will test and determine the root cause of why the CEL is on and how to resolve any problem.

Oil Pressure Light

This oil light indicates that there is a problem with your car’s oil pressure system. Either your engine is low on oil or your oil pump isn’t circulating enough oil to sufficiently lubricate the moving components inside your engine.

This issue should be addressed as soon as possible because the engine can wear or get damaged without proper oil lubrication. Give us a call and we’ll help you diagnose this oil warning light so you don’t have any worries on your next commute!

Anti-Lock Brake System

If this “ABS” Anti-Lock Brake warning lights up while you are driving, it means that something is wrong with the anti-lock system. The anti-lock braking system works to keep your car in contact with the road safely, so it’s important to have our technicians diagnose this issue as soon as possible.

Please note that every time you start your vehicle it does a self-check on the ABS system and the light may come on for a few seconds. If it turns off immediately, it is in good working condition and you are good to go.

Engine Temperature Warning

If you see this engine temp light come on, it means that your engine is overheated. This most likely has to do with your coolant in the radiator, but there could be a number of reasons ranging from a faulty water pump or thermostat failure to a leak in the radiator or engine cooling system.

If your engine is overheating it is important to address this immediately to avoid damage to your vehicle engine. The cooling system for your car is complex but we’ll make it simple for you to understand the diagnostics and any repairs needed. Call us today!
