P2030 OBD-II Trouble Code: Fuel Fired Heater Perf
P2030 code definition
The P2030 code identifies a problem with the fuel fired heating system.
The code is often associated with manufacturer-specific codes indicating issues with the climate control system and the body control module.
What the P2030 code means
P2030 is the OBD-II code for a fault involving the fuel fired heating system. This code is manufacturer-specific, meaning that a number of automotive manufacturers use it but it is not standard in every vehicle’s OBD-II system. This system is in charge of making heat for features like climate control, heated side-mirrors, heated steering wheels, and heated seats. A fuel fired heating system taps into the vehicle’s fuel supply to create heat and supply said heat to various elements throughout the vehicle.
In the case of a climate control system, for instance, a blower motor moves air over a heating element to warm the passenger compartment. A malfunction with this blower motor is often the cause of the P2030 code.
What causes the P2030 code?
The P2030 code has a number of common causes:
- Malfunctioning heating element within the fuel fired heating system
- Faulty blower motor for passenger compartment
- Short on the fuel fired heating system circuitry
- Loose or corroded wiring within fuel fired heating system
What are the symptoms of the P2030 code?
When the P2030 code appears, there will be some notification of it on the dashboard or instrument panel. In many manufacturers, this occurs in the form of the Check Engine light illuminating. Physical symptoms affect only systems responsible for making heat in the passenger compartment and for heated accessories. Features like heated seats, heated mirrors, and a heated steering wheel may not be operational.
How does a mechanic diagnose the P2030 code?
The P2030 code is diagnosed using an advanced OBD-II scanner that is capable of retrieving a wide array of information from the vehicle OBD-II system. A qualified technician will use this tool to not only see the codes that have been stored within the system, but also when the codes were stored. This information will be recorded before the codes are totally reset.
Once the codes are all cleared, the technician will take the vehicle for a test drive. If the same codes appear during the test, then it will confirm that there is a consistent issue.
Common mistakes when diagnosing the P2030 code
Since fuel fired heating systems are not only manufacturer-specific, but also highly uncommon in certain areas (like North America), and are often overlooked when troubleshooting issues with the climate control system. A simple short in wiring near the blower motor has the ability to trigger the P2030 code and prevent the climate control system function.
How serious is the P2030 code?
The P2030 code is not very serious and mostly affects luxury comfort options like heated side mirrors and heated seats. Still, for people living in cold climates, these features can be extremely important for everyday use. It is wise to get the problem diagnosed a short time after the P2030 code appears.
What repairs can fix the P2030 code?
The most common repairs to address the P2030 code are as follows:
- Repair or replace wiring harness around fuel fired heating system
- Repair or replace climate control blower motor
- Repair or replace heating element
Additional comments for consideration regarding the P2030 code
Symptoms associated with the P2030 code are usually only noticeable in cold temperatures. Systems aside from the fuel fired heating system should be unaffected.
