A mechanic can perform a diagnostic test on your Toyota to find potential problems or errors. You’ll need a diagnostic test if your Toyota is making odd noises, not functioning properly, or if your dashboard warning lights are illuminated.
Keeping you and your Toyota safe is important, which is why car insurance super app Jerry is here to break down all you need to know about Toyota diagnostic tests.
The exact cost varies between different Acura models. For example, newer vehicle models are usually made with more expensive materials, so recent or high-end models will cost more, especially if your service requires a part replacement. Use the table below to estimate the cost for your own vehicle.

What is a Toyota diagnostic test?

When performing a Toyota diagnostic test, a mechanic will use a diagnostic scanner to examine your car’s computer system and components.
Since most cars are digitized and contain computer systems, diagnostic scanners can help pinpoint issues with a vehicle before they cause severe damage. The scanner reviews components like:
  • Engine
  • Brakes
  • Transmission
  • Fuel injector
  • Throttle
  • Exhaust system
  • Oil tank
Regularly testing your Toyota ensures it’s well maintained, saving you money in the long run and helping avoid serious damage.

How to complete a Toyota diagnostic test

A mechanic or dealer can complete a Toyota diagnostic test in a matter of minutes.
A mechanic will typically do the following when performing a scan:
  • Plug a diagnostic scanner into your vehicle’s OBD port
  • Run a scan on the entire vehicle
  • Review any error codes the scan finds
  • Inspect any areas the scan flagged
  • Make necessary repairs
  • Rescan the system to ensure its functioning properly
While diagnostic tests are simple, the error codes they produce can be complex. If there are several errors, it could take hours or days to repair your vehicle.

When do I need a Toyota diagnostic test?

If your check engine light is on, your Toyota is making strange noises, or isn’t running as it should—take it in for diagnostic testing.
While diagnostic tests can be run routinely or with regularly scheduled maintenance, it may be necessary to have a test completed immediately if your vehicle is malfunctioning.
If you have a Camry, Corolla, or Prius, always take your car in for diagnostic testing if the check engine light appears, or you notice issues with your automatic transmission. These models are prone to engine and transmission issues, which will require professional diagnosis and repairs.
Even if your Toyota is running like a dream, it never hurts to have diagnostic tests run seasonally or during scheduled maintenance to prevent any minor issues from becoming more damaging or expensive.

How much does a Toyota diagnostic test cost?

A Toyota general diagnostic test usually costs between $88 and $111, not including:
  • Services fees
  • Repairs
  • Taxes
  • Type of car
If your Toyota requires replacement parts or repairs, you can expect to spend more. Owning an older vehicle can almost impact your rate as parts may be difficult to replace.
To help reduce your costs, many auto part retailers and online stores sell OBD scanners. With a scanner, you can regularly scan your Toyota’s system at home without paying a diagnostic fee every time. Another option is visiting the dealership if your Toyota is in warranty or checking with businesses or shops in your area that offer free diagnostic testing.
While you can DIY the test, it’s usually recommended that you visit a professional for any repairs or replacement parts. Even having a professional review the error codes can ensure you don’t miss anything or accidentally damage your vehicle.
