If your canister purge valve is not opening properly, it may adversely impact your gas mileage. If your check engine light turns on, make sure to bring your car to a certified mechanic who can help diagnose the problem.
Common error codes include P0441 and P0446, as well as other EVAP codes. If your car’s computer detects higher or lower than expected purging from the valve, it will illuminate the check engine light.
Your canister purge valve is controlled by your car’s computer, which allows it to monitor its performance. The first sign of trouble for your canister purge valve is the check engine light. The symptoms are listed below that may indicate your canister purge valve is not functioning properly. The most common purge valve issues are when the purge valve is stuck open or closed, or does not open at the proper time. The canister purge valve is electrically operated, and is also referred to commonly as a solenoid. The flow of these vapours is controlled by your canister purge valve, which regulates when and how much of these vapours enter your engine. When your engine begins to run at regular speed, the EVAP system slowly allows these vapours to be released into your engine, which burn like regular fuel. This system restricts the fuel vapours created in your fuel tank from escaping into the atmosphere by trapping them in a charcoal canister. If there is anything you would like to add below, please leave a comment.The canister purge valve, also commonly referred to as the purge valve, is an important component of your Evaporative Emission Control (EVAP) system. P0445 can be somewhat tricky to diagnose.

Here’s a good YouTube video on how to diagnose P0440. You’re going to be looking for frayed and shorted wiring going to the solenoid. If there isn’t voltage at the solenoid, you’ll need to go back and see if there is a wiring issue.
If it is, and the ground is good, it’s almost certainly the solenoid that is at fault. If you don’t hear anything at all, you’ll need to check to see if the purge valve solenoid is getting any voltage. When it opens, you should be able to hear it. You’ll be able to command the purge valve to open.

While it’s not nearly as likely as a wiring issue, or bad purge valve solenoid, or a bad PCM can trigger P0445.Ī good code scanner can really help aid you in diagnosing P0445. How to Find a Short in a Car (Backyard Mechanic) You’ll also want to make sure that the purge valve is getting power to it at all. Take a look at the wiring harness plugged into the purge valve solenoid and see if it looks undamaged and that it is secure. If the wiring harness from the PCM to the purge valve solenoid is frayed or shorted out, the purge valve won’t open and P0445 will be thrown. It could also be a situation where it is stuck open or closed. The wiring in the purge valve solenoid can short out, which means it can’t respond to instructions from the ECM. P0445 indicates a problem with the a short in the wiring harness going to or from the purge valve solenoid, or in the solenoid itself. It may not be perceptible to most people though. Minor Decrease in Fuel Economy– With your Sonic’s air/fuel minute being off, it may cause a minor dip in fuel mileage.Gas Smell– If the purge valve is stuck shut, when the fuel vapor builds up it will escape into the air.Check Engine Light– This is often the only symptom that you’ll see with this code.There typically won’t be much in the way of noticeable symptoms associated with P0445 and your Sonic. P0445 is typically caused by a short circuit (as the code suggests) or by a bad purge valve (stuck open/closed). You may notice a slight smell of fuel as well coming from your Sonic. Otherwise these vapors are sent out into the air. Your vehicle’s Evaporative Emissions Control System is responsible for sending fuel vapor from the gas tank and sending it to the intake, where it can be burned. It’ll usually be accompanied by other codes as well, such P0455. P0445 is typically caused by a short circuit (as the code suggests) or by a bad purge valve (stuck open/closed).īefore you do anything, make sure the gas cap is on and sealed tightly. It indicates that there is a short circuit in the Evaporative Emissions Control (EVAP) System. It’s generic, which means that it has the same meaning for the Chevy Sonic as it would for any other vehicle.
