Watching Your Check Engine Light

Posted January 1, 2022 7:31 AM

Did you know that most of the cars driving around Riverside, CA, carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in the Riverside area have as many as 12 networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle's functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do Riverside drivers know when there is a problem?

It's simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing for Riverside drivers when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to Protrans Automotive & Transmission Specialists in Riverside to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

Your friendly and knowledgeable technicians at Protrans Automotive & Transmission Specialists have special diagnostic equipment that will retrieve the trouble code from the computer and help him determine what is wrong. From there, we can fix it and get you back on the road.

Stop by if you're Check Engine light is on.

what our customers say

We've been going to Pro Trans for over 20 years & always have good experiences. I want to thank Michael for his personal service all these years. They've replaced engines & transmissions in two of our vehicles. There is no job too small or too big, so far. They don't even mind working on our raised truck with a 6 inch lift! Thanks again for your the great work!

I was nervous about finding a shop to work on my truck since there are so many shady mechanics out there, but Protrans ended up doing an amazing job. They were great about communicating with me throughout the whole process as well. I believe I paid a fair price for the repair and they didn't try to sell me a bunch of service that I don't need. I will certainly be using them in the future if I need to.

The crew at Protrans replaced my fuel tank after thrives drilled a hole in my existing tank and had my truck back to me in a day and a half. Thanks again!

The team at Protrans are professional and service minded. They performed a synthetic oil change on my sister's Chevy Cruze swiftly and seamlessly. It was my first time using this company and I will definitely be going back. A shout out of thanks to Jeff, Manny, Haley and the the entire Protrans team!
