“My check engine light came on yesterday,” David sighed, pulling up to the counter at Mike’s Auto Parts. “It’s my Honda Element, and the code reader says it’s P1157. Any idea what that means?”
Sound familiar? If you’re a Honda Element owner, you might have encountered this cryptic code yourself. Don’t worry, deciphering OBD codes doesn’t have to be as mysterious as deciphering ancient hieroglyphs. Let’s break down P1157 and what it means for your Honda Element.
What the “Check Engine” Light Really Means
Your car’s computer, also known as the Engine Control Module (ECM), is constantly monitoring various systems. When it detects something unusual, it triggers the “check engine” light and stores a Diagnostic Trouble Code (DTC) in its memory. In this case, P1157.
P1157: Breaking it Down
The code P1157 in your Honda Element specifically points to an issue with the Air Fuel Ratio (A/F) sensor heater circuit. Think of the A/F sensor as your car’s “taste tester,” constantly analyzing the exhaust gases to ensure the right mixture of air and fuel is entering the engine. The heater circuit ensures the sensor reaches optimal operating temperature quickly, particularly in cold weather.
Why Does it Matter?
A properly functioning A/F sensor is crucial for:
- Fuel Efficiency: The correct air-fuel mixture ensures your engine burns fuel efficiently, saving you money at the pump.
- Optimal Performance: The right blend means your engine runs smoothly and delivers its best performance.
- Reduced Emissions: A well-tuned engine produces fewer harmful emissions, benefiting the environment.

Common Causes of P1157
Several culprits could be behind the P1157 code in your Honda Element:
- Faulty A/F Sensor: This is the most common cause. The sensor itself might be worn out or damaged.
- Wiring Problems: Damaged, corroded, or loose wiring in the sensor circuit can disrupt the signal.
- Blown Fuse: The heater circuit has a dedicated fuse, which might have blown.
- Faulty ECM (Rare): In rare instances, the ECM itself might be malfunctioning.
Taking Action: What to Do Next
Seeing the P1157 code doesn’t necessarily mean a trip to the mechanic is in your immediate future. However, ignoring it can lead to more serious problems down the road. Here are some steps you can take:
- Verify the Code: While your initial code reader might have pointed to P1157, it’s best to double-check with a more advanced OBD-II scanner, preferably one designed for Honda vehicles.
- Check the Simple Stuff: Before diving into costly repairs, start with the basics. Inspect the A/F sensor fuse (consult your owner’s manual for its location).
- Consult a Professional: If the problem persists, it’s best to seek help from a qualified mechanic specializing in Honda vehicles. They have the expertise and tools to diagnose the issue accurately and perform the necessary repairs.

FAQs About Honda Element P1157
Can I still drive my Honda Element with code P1157?
While you might be able to drive short distances, it’s not recommended. Ignoring the code can lead to decreased fuel efficiency, reduced engine performance, and potentially more severe engine problems.
How much does it cost to fix P1157?
The cost can vary depending on the root cause and your location. A simple fuse replacement could be inexpensive, while replacing the A/F sensor itself can be more costly.
