P0133 2017 Honda CR-V Code - Air/Fuel Ratio Sensor 1 Malfunction/Slow Response
Quick Answer
The Air/Fuel Ratio (A/F) Sensor (Sensor 1) is responsible for measuring the oxygen concentration in the exhaust gas and providing this information to the Powertrain Control Module (PCM). Common causes include Faulty Air/Fuel Ratio (A/F) Sensor (Sensor 1), A/F Sensor (Sensor 1) harness is open or shorted, A/F Sensor (Sensor 1) circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0133 2017 Honda CR-V Description
The A/F Sensor (Sensor 1) has a linear signal output in relation to the oxygen concentration. This means that the higher the oxygen concentration in the exhaust gas, the higher the voltage output from the sensor. The PCM converts this voltage output to an air/fuel ratio value, which it then uses to adjust the fuel mixture in the engine.
The PCM also compares the response characteristics of the A/F Sensor (Sensor 1) to a set of predetermined values. If the sensor's response is outside of these predetermined values, the PCM will store a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0133 2017 Honda CR-V?
- Faulty Air/Fuel Ratio (A/F) Sensor (Sensor 1)
- A/F Sensor (Sensor 1) harness is open or shorted
- A/F Sensor (Sensor 1) circuit poor electrical connection
How to Fix the DTC P0133 2017 Honda CR-V?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0133 2017 Honda CR-V Code
1. What are the common symptoms of OBDII code P0133 in a 2017 Honda CR-V?
- Common symptoms include poor fuel economy, rough idling, hesitation during acceleration, and an illuminated Check Engine light.
2. What causes the OBDII code P0133 in a 2017 Honda CR-V?
- The code P0133 is typically triggered by a malfunction or slow response from the Air/Fuel Ratio Sensor 1, also known as the upstream oxygen sensor.
3. How can I diagnose the cause of OBDII code P0133 in my 2017 Honda CR-V?
- To diagnose P0133, you can use an OBDII scanner to read the code, visually inspect the sensor and its wiring, check for exhaust leaks, and perform testing on the sensor's response.
4. Can a dirty or contaminated Air/Fuel Ratio Sensor cause code P0133 in a 2017 Honda CR-V?
- Yes, a dirty or contaminated sensor can lead to inaccurate readings and trigger code P0133. Cleaning or replacing the sensor may resolve the issue.
5. Is it safe to continue driving with OBDII code P0133 in my 2017 Honda CR-V?
- While the vehicle may still be driveable with code P0133, it is recommended to address the issue promptly to prevent potential long-term damage to the engine or catalytic converter.
6. What are some repair tips for fixing OBDII code P0133 in a 2017 Honda CR-V?
- Repair tips include checking for exhaust leaks, ensuring proper sensor installation, verifying wiring integrity, and using a high-quality replacement sensor if needed.
7. How do I reset the Check Engine light after repairing OBDII code P0133 in my 2017 Honda CR-V?
- To reset the Check Engine light, you can use an OBDII scanner to clear the code, or disconnect the car battery for a few minutes to reset the vehicle's computer.
8. What is the role of the Air/Fuel Ratio Sensor in a 2017 Honda CR-V and how does it affect engine performance?
- The Air/Fuel Ratio Sensor monitors the oxygen content in the exhaust gases, helping the engine's computer adjust the fuel mixture for optimal combustion. A malfunctioning sensor can lead to poor engine performance.
9. Can extreme weather conditions or driving habits contribute to triggering OBDII code P0133 in a 2017 Honda CR-V?
- Yes, extreme weather conditions, prolonged idling, or frequent short trips can impact the performance of the Air/Fuel Ratio Sensor and potentially trigger code P0133.
