Yes, Penny, you may want to check out that Check Engine light

penny and sheldon cooper check engine light
Sheldon Cooper:
Your check engine light is on.

Penny:
Mm-hmm.

Sheldon Cooper:
Typically that's an indicator to, you know, check your engine.

Penny:
It's fine, it's been on for, like, a month.

Sheldon Cooper:
Well, actually, that would be all the more reason to, you know, check your engine.

Penny:
Sheldon, it's fine.

Sheldon Cooper:
If it were fine, the light wouldn't be on. That's why the manufacturer installed that light, to let you know it's not fine.

Penny:
Uh, maybe the light's broken.

Sheldon Cooper:
Is there a "check the check engine light light"?

In the television show Big Bang Theory there’s an episode where Penny is driving Sheldon Cooper in her car. With his neurotic nature, Sheldon is deeply disturbed that Penny’s “Check Engine” light is on. Penny reassures him that it’s been on for a long time; it’s nothing to worry about.

Is Penny right or does Sheldon, regardless of his obsessive-compulsive behavior, have a point?

Depending on how you look at it, the light doesn’t necessarily mean that the engine will melt into a single blob of metals at any moment. Then again, the manufacturers build the lights into the dashboard for a reason. It could very well indicate something you want to look at sooner than later. Even if it’s nothing earth shaking, it’s better to address the concern now. And, if you have to bring the car in to Crystal Lake for an Illinois Emissions Test, the light would cause your car to fail the test.

As long as we’ve opened this can of worms, what could the Check Engine light indicate? The light could refer to possible problems with the following parts:


  • Ignition parts: distributor cap, spark plugs and/or spark plug wires
  • Evaporative emissions purge control valve
  • Mass airflow sensor
  • Evaporative emissions purge solenoid
  • Oxygen sensors
  • Catalytic converter
  • Fuel injectors
  • Thermostat
  • Loose or leaking gasoline cap


In other words, there is a wide range of potential problems that might cause the Check Engine light to stay on. The problems do not, necessarily, require expensive repairs. However, all of the problems could affect the efficiency of the engine’s operation and could lead to additional problems if not taken care of promptly.

In other words, if your Check Engine light is staying on, your engine is trying to tell you something. It’s a good idea to listen. You can always stream an episode of Bing Bang Theory while your trusted auto repair shop resolves the issue.

Is your antifreeze safe from freezing this Richmond winter

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing?  If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond  winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...

Blocks of ice falling from cars in McHenry could cause accidents or damage

We’ve all seen those blocks of snow falling from behind the rear tires of a car when the snow rolls into McHenry . Fortunately, they’re just packed snow that will disintegrate under your vehicle’s tires as you simply drive right through them, right? Don’t count on it. Those blocks of snow are often packed so tight, condensed by the thaw-and-freeze cycle, that they’re anything but oversized snowballs . They’re often more like boulders.  Hit one of those blocks and the collision between the block and one of your tires could send you careening off the road or into oncoming traffic. In some cases, they’re so solid you could pound them with a sledgehammer with little effect. They truly can represent a serious road hazard. The problem is that it’s difficult to tell how solidly they’re packed when you see them on the road, left their unwittingly by another driver. Either way, your best bet is to try to avoid them. But you want to be careful dodging blocks of ice in the road, too. You need...

October 20 Hootenanny will benefit veterans with PTSD

Been to a Hootenanny lately? When you read that question did you ask, “What?” Well, if you have gone to a Hootenanny in a while, or if you don’t know what a hootenanny is, we have an event for Oct. 20 that will clear up either question. From 6 p.m. to Midnight, Saturday, Oct. 20, MC3, the McHenry Area Chamber of Commerce business networking group, is helping to host an inaugural Veterans R&R Wild Horse Hootenanny at Beyond Stable Farm (11129 Rte. 176, Woodstock). The event will benefit Veterans R&R Operation Wild Horse. Operation Wild Horse serves veterans with PTSD (Post-Traumatic Stress Disorder). Working with the horses has proven to have an incredibly calming effect on the veterans. And, it’s good for the horses, too, rescued wild mustangs. This means that the hootenanny is for a very good cause. But, it’s also a lot of fun. So, what is a hootenanny? According to a Google search, a hootenanny is “an informal gathering with folk music and sometimes dancing.” The V...
