This summary uses the existing diagnostic information shown in full below.
This code means that a part of the car that controls air and fuel isn't getting enough power. It's like when a toy doesn't work because the batteries are low.
The code indicates that the Air Fuel Control Module (AFCM) is detecting a low voltage signal from the power relay circuit, which is responsible for providing power to the module.
The P2A36 code is triggered when the Engine Control Module (ECM) detects a low voltage condition in the AFCM power relay sense circuit. This circuit is crucial for the operation of the AFCM, which manages the air-fuel mixture for optimal engine performance. A low voltage signal could indicate a problem with the relay, wiring, or connections.
• Check Engine Light is on
• Poor engine performance
• Increased fuel consumption
• Faulty AFCM power relay
• Poor electrical connections in the circuit
• Damaged wiring in the AFCM circuit
AFCM: Air Fuel Control Module
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the AFCM power relay for damage or malfunction.
• Check the wiring and connections in the AFCM circuit for corrosion or damage.
• Replace the faulty AFCM power relay.
• Repair or replace damaged wiring.
• Ensure all electrical connections are clean and secure.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford Focus
• Regularly inspect electrical connections for corrosion.
• Ensure the battery and charging system are in good condition.
• Perform routine maintenance checks on the vehicle's electrical system.
Sensor Issue
• If the Check Engine Light is on, have the vehicle inspected as soon as possible.
• Avoid driving the vehicle aggressively until the issue is resolved.
Check with your vehicle manufacturer as some powertrain warranties may cover this issue.
This code has been associated with issues in vehicles with aging electrical systems or those exposed to harsh environmental conditions.
Moderate – It's important to address this issue to prevent further engine performance problems.
Driving with a malfunctioning AFCM can lead to increased emissions and reduced fuel efficiency.
• Vehicle must be running.
• Electrical load conditions should be normal.
The AFCM power relay is typically located in the engine compartment fuse box.
Q: Can I drive with a P2A36 code?
A: It's not recommended to drive for extended periods with this code as it can affect engine performance.
Q: How can I prevent this issue?
A: Regular maintenance and inspection of the vehicle's electrical system can help prevent this issue.
