Ron Ananian The Car Doctor

The radio show episode revolves around automotive diagnostics and maintenance, led by host Ron Ananian, the Car Doctor. Here’s a summary of key topics discussed:

Main Discussion: Diagnosing a Fuel and Engine Issue

Case Study: A 2019 Honda CR-V with a check engine light and a mechanical ratcheting noise. The vehicle presented a lean fuel condition, which means it required more fuel enrichment to run efficiently.

Diagnostic Process:

Ron analyzed the car’s fuel trim, mass airflow readings, and calculated load to pinpoint the issue.

He discovered that the vehicle had been fueled with high-ethanol gas (likely E85), which is not suitable for standard vehicles. This led to poor engine performance and low oil levels.

The resolution involved running out the improper fuel, conducting an oil change, and educating the owner about proper fuel selection.

Advice for Travelers:

Fuel Awareness: Drivers should be cautious when refueling outside their usual area. Understanding ethanol content (E10, E15, E85) is essential, as high ethanol levels can damage engines not designed for it.

Prevention: Always check fuel pump labels and avoid misfuelling to prevent costly repairs.

Listener Call: 2009 Honda Accord with Express Window Issue

Problem: The car’s windows sporadically rolled down on their own. A history of water leaks in the vehicle was noted.

Possible Causes:

Corroded connections or switches due to water damage.

A malfunction in the express-down function, possibly triggered by a faulty key fob or door unlock switch.

Solution: Ron advised inspecting the driver's side junction block and A-pillar area for corrosion and testing the express-down feature for a reset option.

General Takeaways:

Diagnostic Philosophy: Ron emphasized listening carefully to customer descriptions and methodically checking vehicle systems, likening it to a doctor evaluating a patient.

Practical Tips: Be aware of environmental factors like water intrusion and their potential impact on electrical systems.

Listeners were encouraged to call in with questions and access podcasts for more insights. The episode exemplifies Ron’s hands-on approach and practical advice for car owners.
