Why Perform an Engine Diagnosis When the Check Engine Light Illuminates?

When your check engine light illuminates, a service code will be generated and stored in one or more of your vehicle’s computers. There are specific conditions that have to be met for a trouble code to set, and it is vitally important that the technician who is diagnosing your car checks all of them before he/she makes a repair decision.

The diagnostic trouble code (or DTC) takes you to an area for further testing to properly determine where the real fault is. The diagnostic allows us the time to thoroughly test and accurately determine the real cause of the warning light using the professional test equipment we have invested in.

At Otobots, our technicians have access to a vast database system to help us to provide you with an accurate diagnosis of your vehicle’s engine problem and a repair that is done correctly the first time.

Still not sure if your vehicle’s engine needs servicing? Read our FAQ’s:


A: A no-start condition is one of the most frequently encountered engine problems. If there is a clicking noise but the engine does not crank it generally indicates a battery issue. An engine that cranks but will not start is indicative of a fuel or ignition problem. Common reasons an engine won’t start: Low or discharged battery, corroded or loose battery cables, starter motor relay failure, ignition switch failure, defective fuel pump, clogged fuel filter.


A: The service engine light is designed to illuminate whenever a fault is detected in any of the sensors attached to the emission, engine, or powertrain controls. The purpose of the service engine soon light is to alert the driver to a potentially serious fault that requires repair. An Otobots ASE certified mechanic can retrieve the trouble codes from within the onboard electronic control module and determine the specific cause. Frequent service engine soon light causes: loose or missing gas cap, spark plugs or wires that are worn out or damaged, electronic control module failure, defective distributor or coil packs, emissions control fault such as the oxygen sensor, fuel quality issue.


A: Overheating is most generally caused by a low coolant level. A quick check of the coolant overflow reservoir will indicate if coolant is leaking, and frequent overheating can cause serious and expensive engine damage. Proper maintenance of the cooling system is vital in order to maintain the quality of the coolant and to make certain the cooling system is in good operating condition. Common reasons for overheating: faulty thermostat, dirty or low coolant level, non-functioning cooling fan, kinked or broken radiator hose, internal or external coolant leak, defective radiator cap, dirty air filter.
