P1443 code on a Ford Ranger description
A P1443 code on a Ford Ranger is related to the vehicle’s Evaporative Emission Control (EVAP) System. The code specifically indicates a malfunction within the EVAP Purge Flow Sensor circuit.
The EVAP system is designed to capture fuel vapors from the fuel tank and store them in a charcoal canister. These vapors are then purged into the engine to be burned during the combustion process, which helps reduce harmful emissions and improve fuel efficiency.
The EVAP Purge Flow Sensor is responsible for monitoring the flow rate of fuel vapors being purged from the charcoal canister to the engine.
When the vehicle’s engine control module (ECM) detects a problem with the purge flow sensor’s signal or circuit, it triggers the P1443 code, and the Check Engine Light is illuminated.
Possible symptoms of a P1443 code on a Ford Ranger may include a lit Check Engine Light, decreased fuel efficiency, difficulty starting the vehicle, a fuel odor near the vehicle, and failing an emissions test.
To address a P1443 code on a Ford Ranger, it’s essential to diagnose the issue using an OBD-II scanner, inspect and test the relevant EVAP system components, and repair or replace any faulty parts.
It’s always advisable to consult the vehicle’s service manual for specific testing procedures and specifications, as well as seeking professional assistance if necessary.
How much does it cost to diagnose the P1443 code on a Ford Ranger?
The cost to diagnose a P1443 code on a Ford Ranger can vary depending on several factors, such as your location, the specific model and year of your vehicle, and whether you choose to diagnose the issue yourself or take the vehicle to a professional mechanic or dealership.
- DIY diagnosis: If you have an OBD-II scanner, you can diagnose the code yourself at little to no cost. OBD-II scanners range in price from around $20 for basic models to several hundred dollars for more advanced versions.
- Professional diagnosis: If you choose to have a professional mechanic or dealership diagnose the P1443 code, the cost can range from $75 to $150 or more, depending on the labor rates in your area and the complexity of the diagnostic process.
Keep in mind that the cost mentioned above is for diagnosing the P1443 code only. If repairs are needed, additional costs for parts and labor will apply. It’s essential to obtain a detailed estimate from the mechanic or dealership before authorizing any repairs.
