Fault code U0073 is another code that is irritating. We’ve heard it all before: “This problem is like a puzzle!” And in this case, it’s not just a metaphor—it’s actually true! The U0073 fault code can be caused by several different things, and figuring out which one is the source of your issue requires knowledge and experience with vehicles. If you’re looking for help understanding what this code means and how to fix it, read on!
What it means
The U0073 DTC is related to a problem with the powertrain control module (PCM). There are several common causes of this trouble code, including:
- A bad PCM
- Faulty wiring or connectors
- Water or debris in the engine oil pan or filter housing
How to fix it
There are a few basic things you can do to check whether your battery is at fault. You’ll need an assistant and a multimeter to perform these tests, but they should be simple enough for anyone who has done this kind of car repair before.
- Check the battery terminals by making sure they’re clean and tight-fitting against the terminal posts on your battery. If there’s corrosion or anything preventing a good connection here, try cleaning with some sandpaper or steel wool to remove any build-up and then reapply some dielectric grease (available at auto parts stores) before reattaching them to the post.
- Next, test the voltage output of your alternator by connecting one lead from your multimeter set in DC volts mode directly across two points on its positive terminal (which will also be labeled V+) and negative (-) terminal respectively; you should see around 14 volts if it’s working properly—if not then replace it!
- Finally try jumping out this next step if possible: Check all wiring going into both ends of your new battery; make sure that none are loose or frayed – reattach any that look suspiciously bad – now see if starting works again? If not then check those other steps again until everything checks out okay..

What does the fault code U0073 mean?
The fault code U0073 indicates that the transmission is not responding to the throttle pedal. This may indicate a problem with the throttle position sensor or transmission control module.
Fault Code U0073: Throttle Position Sensor (TPS)
The TPS monitors how far down you press your gas pedal, and sends that information to your vehicle’s computer. If it gets an inaccurate reading, it will cause problems with shifting gears and cause other issues as well. To fix this problem, you need to replace your faulty TPS.
When does the fault code U0073 appear?
The U0073 fault code will appear when the vehicle’s computer detects a problem with your car’s transmission system. When this error is detected, your vehicle will turn off and refuse to start until the problem has been fixed.
Know your fault codes so you don’t accidentally fix things that weren’t broken to begin with.
- Now that you know what fault code U0073 means and how to deal with it, don’t forget to take the time to understand your other fault codes.
- Depending on whether the problem was electrical or mechanical in nature, you might need a different solution for each one.
- Remember: If you aren’t sure about a particular fault code, it’s best not to try fixing things on your own unless you have a lot of experience doing so—and even then, asking an expert may be best!
