Have your engine analyzed today.

Computerized Engine AnalysisVehicles used to need regular tune-ups as older vehicles have carburetors with tuners on them. These tuners control the ratio of fuel and oxygen delivered to the engine. Modern vehicles use an ECM (Electronic-control-module) and this computer chip is the brain of your vehicle. It performs on the fly regulation with data gathered from all of the sensors in and throughout your vehicle.

Our technicians diagnose and repair your engine problems.

An ECM lets you know when something is wrong and a developing problem will result in a lit check engine light. It also sends a code or several codes to be stored and retrieved by professionals. Because European and Import vehicles are such a finely tuned machines you shouldn’t have repairs performed by just any shop. At Tech Plus Automotive we only use the latest manufacturer approved equipment. Our technicians use these diagnostic machines to read your vehicle’s control computer and measure your current sensor readings against factory recommended specifications. If something doesn’t function correctly our technicians can repair it on-site with OEM or OEM spec replacement parts. We currently service popular European and Import brands including; Acura, BMW, Infiniti, Jaguar, Land Rover, Lexus, Mercedes, Porsche and Volvo.

Why is my check engine light lit?

Sensory components continuously transmit data to the ECM. There are three different control systems in your vehicle. These regulate your emissions, fuel system and ignition. A warning is triggered when this data falls outside of your vehicle’s factory set parameters. We will determine if your warning light is on due to error or if it signals a greater problem. The easiest way to avoid problems is to service your vehicle regularly. Unfortunately, car parts cannot be made to last forever as heat and movement wear components down over time. If you drive long enough in Scottsdale you will need to replace them.

What sensory components are in my vehicle?

  • The mass airflow sensor regulates how much oxygen your intake system pulls.
  • A throttle position sensor monitors throttle levels.
  • Your manifold absolute pressure sensor controls the fuel injection rate.
  • A coolant temperature sensor tells you if your vehicle is overheating.
  • The exhaust oxygen sensor measures emission and oxygen levels.
  • Your crankshaft position sensor helps control timing.
  • A camshaft position sensor monitors crankshaft rotation speed.
