Ron Ananian "The Car Doctor" Radio Show:

Ron opens the show by discussing recent media appearances, particularly focusing on dashboard warning lights, with a segment on the check engine light drawing significant listener interest across social media platforms. Ron then takes us on a deeper dive into the check engine light; what it means when it turns on and then off intermittently, He emphasizes that modern cars constantly self-test their systems—especially emission-related components—and even transient issues can trigger the light.

Ron stresses the importance of capturing diagnostic trouble codes (DTCs) as soon as the light appears, either with a personal scanner, a visit to a parts store, or by asking a trusted mechanic. He discusses common causes like fuel blend issues, oxygen sensor faults, and catalytic converter efficiency (e.g., codes P0420 and P0430). He explains how systems like freeze frame data provide vital context, such as engine conditions at the time of failure, and why clearing codes prematurely can erase that valuable info.

He criticizes the "head-in-the-sand" approach many car owners take, warning against ignoring warning lights before long trips. To drive home the point, he likens a car's self-check to a person’s morning routine—each check step can reveal issues before they become major.

In the second half, a caller named John discusses an intermittent starting problem on his 2003 Chevy Impala. After replacing a crank sensor and checking the fuel system, John discovers that the ignition control module was the root cause. Ron walks through his logical diagnostic approach, including checking spark color, using plastic tubing to test for fuel leaks, and watching for rodent damage (which John found). Ron commends John for his solid diagnostics and suggests replacing the coils as preventative maintenance.

In a later call, a listener named Joe describes a 2010 Impala stuck in park due to a shifter issue. Ron begins diagnosing by asking if the brake lights work—implying a possible brake switch or shift interlock solenoid failure. He continues to diagnose the problem for all; except for the caller, whom does not seem to be listening.

Ron closes with show updates, reminding listeners about a new YouTube video on diagnosing a fuel pump issue in a 2015 Tacoma and reminds everyone about his available T-Shorts and merchandise found on his website.
