P0443 on a 2022 Toyota Camry
EVAP Purge Valve Circuit Fault
P0443 on a 2022 Toyota Camry indicates evap purge valve circuit fault. It usually stays drivable short-term but should be diagnosed promptly. The most common cause is failed evap purge valve solenoid (open or shorted coil) (typically $80–$300). Confirm the root cause before replacing parts.
What does P0443 mean on a 2022 Toyota Camry?
P0443 is an electrical code. The ECM drives the EVAP purge control solenoid and monitors that circuit; when the voltage or current it measures does not match what the commanded state should produce — an open coil, a short to ground, or a short to power — P0443 sets. It says nothing about whether vapor is actually flowing, which is what P0441 measures. P0443 means the circuit itself is not electrically healthy, so the test starts with a multimeter rather than a smoke machine.
The symptoms, causes, and diagnostic steps below describe P0443 itself, so they read the same on nearby Toyota Camry model years. Powertrain and trim details vary year to year — confirm the specifics against your own vehicle before buying parts.
Is it safe to drive a 2022 Toyota Camry with P0443?
In most cases a 2022 Toyota Camry stays drivable for short trips with P0443 active, but diagnose and repair it promptly. This is a low-severity code — ignoring it can lead to further damage or a failed emissions test.
What are the symptoms of P0443 on a 2022 Toyota Camry?
- Check Engine Light is illuminated
- Often no drivability symptoms at all
- Rough idle or stalling if the solenoid has failed in the open position
- Hard start after refueling (solenoid failed open)
- EVAP readiness monitor will not complete
- Vehicle will fail emissions / smog testing
What causes P0443 on a 2022 Toyota Camry?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Failed EVAP purge valve solenoid (open or shorted coil) | Most common | $80–$300 |
| Damaged or corroded wiring / connector at the purge valve | Common | $50–$250 |
| Blown fuse feeding the purge solenoid circuit Cheap to check and cheap to fix — do it before ordering a solenoid. | Occasional | $5–$30 |
| Aftermarket purge valve with a coil resistance outside the ECM's expected range | Occasional | $80–$300 |
| Failed PCM driver for the purge solenoid | Rare | $400–$1,500 |
Cost ranges are editorial estimates for parts and labor at an independent U.S. shop — not quotes. What you actually pay moves with your region, the shop's hourly rate, which engine you have, and how much diagnostic time the job takes. Dealer service departments typically sit above these ranges.
How to diagnose this on a 2022 Toyota Camry
-
Locate the purge valve and inspect the connector
On most vehicles the purge solenoid sits in the engine bay, in the hose run between the charcoal canister and the intake manifold. Unplug it and inspect for green corrosion, spread pins, or oil and coolant intrusion. Engine-bay connectors bake for years; a bad connector is far more common than a bad PCM.
Tools: Connector unlock tool, Flashlight, Electrical contact cleaner
-
Measure the solenoid coil resistance
With the connector off, measure across the two solenoid terminals. Most purge solenoids read somewhere in the tens of ohms — check the service manual for the exact figure for this vehicle. An infinite reading means an open coil. A near-zero reading means a shorted coil, and it will often take the fuse with it.
Tools: Multimeter, Wiring diagram
-
Check for supply voltage and a PCM-side ground
Purge solenoids are normally fed battery voltage on one side and switched to ground by the PCM on the other. Key on, back-probe the supply wire — you should see battery voltage. Then confirm the PCM pulls the other side to ground when purge is commanded. Missing supply voltage points upstream at the fuse or the relay, not at the valve.
Tools: Multimeter, Back-probe pins, Wiring diagram
-
Check the fuse that feeds the circuit
Find the fuse for the EVAP / emissions circuit in the underhood box and test it with a test light rather than trusting a visual check. If a replacement fuse blows immediately, you have a hard short — usually a chafed wire or a shorted solenoid coil, not a PCM problem.
Tools: Test light or multimeter, Replacement fuse
-
Command the valve with a bidirectional scan tool
With the connector plugged back in, command the purge valve on and off while listening at the valve body. A healthy solenoid clicks crisply each time. Silence with confirmed voltage and ground at the connector means the solenoid is dead internally.
Tools: Bidirectional scan tool with EVAP purge command

Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.
NHTSA #11028712 - ENGINE Aug 7, 2025
The specific condition covered by this program is for a small engine coolant leak that can occur from the flow shut-off valve that can allow coolant to drip on other parts of the vehicle. This can cause "Engine Maintenance Required" to be displayed on the instrument cluster or cause the A/C not to function normally. Although the flow shut-off valve is covered by Toyota’s New Vehicle Limited Warranty for 36 months or 36,000 miles (whichever comes first), we at Toyota care about the customers’ ownership experience. Toyota is providing coverage for repairs related to Flow Shut-off Valve Coolant Leak.

Engines in the 2022 Toyota Camry
The 2022 Toyota Camry was offered with the 2.5L 4-cylinder and 3.5L 6-cylinder engines, including a hybrid version. Which one you have changes where P0443 is most likely to originate, so confirm your engine before ordering parts.
Engine data: EPA fueleconomy.gov.
P0443 vs P0441
These two get confused constantly, and they lead to different repairs:
- P0443 — the circuit is faulty. The ECM cannot electrically drive the solenoid, or the feedback it reads is wrong. Test with a multimeter.
- P0441 — the flow is wrong. The circuit may be perfect, but vapor is not moving. Test with a vacuum pump and fuel trim data.
If both set together, fix the electrical fault first. A solenoid that cannot be driven obviously cannot flow, so P0441 will often clear on its own once P0443 is resolved.
Test the circuit before you buy the valve
The purge solenoid is one of the most-replaced parts in the EVAP system, and a fair number of those replacements do not fix anything. Two ten-minute measurements — coil resistance at the valve and supply voltage at the connector — tell you whether the problem is the part or the wiring feeding it. The valve is cheap enough that guessing is tempting; the wiring repair you skipped will set the code again in a week.
Aftermarket parts and circuit codes
The ECM on many modern vehicles measures the actual current through the solenoid, not just whether the circuit is complete. A cheap aftermarket valve with a coil resistance outside the OEM window can draw the wrong current and set P0443 while working mechanically. If P0443 appeared shortly after someone installed a non-OEM purge valve, that valve is the first thing to suspect.
Living with P0443
The car drives normally in most cases, and the fault does not damage anything mechanically. What it does do is guarantee an emissions failure and prevent the EVAP monitor from ever completing. There is no urgency in the “pull over now” sense — but it is not going to fix itself either, and vapor that should be burned in the engine is being vented instead.
