Circle Automotive understands the importance of your On-Board Diagnostics. Give us a call or stop by for a complete diagnostic check up:
Check Engine Light
No one likes to see their truck's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At Circle Automotive, we can pull the code and diagnose the problem for you. Give us a call at 559-325-9585 or stop by the shop for our expert assistance.
Computer Diagnostics
Modern vehicles are fitted with at least one onboard computer. The computer's main function is to monitor and adjust the engine and transmission. Computer testing and diagnostics is an integral aspect to professional electronic work on modern cars. Computer diagnostics help find the root causes of major and potential automobile problems. At Circle Automotive, we have state of the art computer diagnostics equipment such as digital code readers, pressure test kits, circuit testers, digital tachometers and more. Call 559-325-9585 or visit our auto shop in Clovis, CA 93611 for all your vehicle's computer diagnostic needs.
Drivability
Drivability is the degree of smoothness and steadiness of your truck's acceleration. Most modern vehicles are fitted with on-board computers that continuously check the readings from various sensors. In case of drivability problems, you will receive a warning message on your truck's dashboard. To have your truck diagnosed for drivability issues, visit Circle Automotive in Clovis, CA 93611 today. At Circle Automotive, we have the necessary tools, training, and technology to diagnose and address your vehicle's drivability issues.
Engine Controls
Basically, an engine control system is an on-board computer in your truck. Like all computers, the engine controls are composed of hardware and software. Automotive engine control systems are responsible for regulating exhaust emissions, and providing increased fuel economy. To get the best out of your vehicle's incredibly powerful technology, make sure engine controls are working properly. To check if your truck's engine controls are working properly, call Circle Automotive today.

Clovis, CA
Blessed to have come upon this shop. My family and I were on a road trip from New York and our car broke down near Clovis at 8pm on Friday. Our Honda Odyssey couldn't take the hilly up and downs of the Cali hills. AAA towed us to this shop but since it was late we would have to wait till the morning to talk to anyone about the work. The shop says it's only open weekdays and Saturday by appt. So we decided we would come in the morning and possibly someone would be there working. We came back the next morning and John was there. He is a very generous and caring man. He decided to look at our car to see what's wrong and ended up helping us out. The day before, we already were thinking the road trip is down and out, and the super old car is dead. Everything was amazing, from the service to the conversations. Huge thank you to John!!
We've gone to Circle Automotive a few times, and each time we received excellent service with a friendly staff.
