Most auto repair shops typically charge between $75 and $150 per hour for their services. These factors contribute to the overall cost of resolving the p1444 fault code.

The P1444 fault code refers to the EVAP Canister Purge Volume Control Solenoid Valve. This valve is responsible for controlling the flow rate of fuel vapor from the EVAP canister.

It works by opening and closing the vapor bypass passage in the canister to regulate the flow rate. The Engine Control Module (ECM) sends a signal to the solenoid valve, which then operates in an ONOFF pattern. The valve’s opening varies to achieve optimal engine control, with the ECM storing the ideal value based on different engine conditions.

As the engine operates, the flow rate of fuel vapor from the EVAP canister is regulated to match changes in air flow.

What are the possible causes of the automobile fault code P1444?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P1444 could be the culprit. This code is often caused by a faulty EVAP control system pressure sensor, a stuck open EVAP canister purge volume control solenoid valve, a faulty EVAP canister vent control valve, faulty or broken EVAP canister, or incorrectly connected or clogged hoses. To fix the issue, visually inspect the wiring harness and connectors, check for damaged components, and look for any broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the P1444 fault code?

If you’re dealing with the P1444 fault code and your engine light is on, it’s time to take a closer look at the wiring harness and connectors.
