P0135 2017 Honda CR-V Code - Air/Fuel Ratio Sensor 1 Heater Circuit Malfunction

Quick Answer

A heater for the sensor element is embedded in the Air/Fuel Ratio (A/F) Sensor (Sensor 1), and it is controlled by 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.

What it means: P0135 2017 Honda CR-V indicates Air/Fuel Ratio Sensor 1 Heater Circuit Malfunction.
Common causes: 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: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0135 2017 Honda CR-V Description

A heater for the sensor element is embedded in the Air/Fuel Ratio (A/F) Sensor (Sensor 1), and it is controlled by the Powertrain Control Module (PCM). It is activated and heats the sensor to stabilize and speed up the detection of oxygen content when the exhaust gas temperature is cold. The PCM monitors the A/F Sensor (Sensor 1) heater output (return check). If the return signals do not meet the command value (for heater activation) for a set time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).

Frequently Asked Questions about P0135 2017 Honda CR-V Code

1. What does the OBDII code P0135 mean on a 2017 Honda CR-V?

P0135 indicates a malfunction in the heater circuit of the Air/Fuel Ratio Sensor 1, which helps the sensor reach operating temperature more quickly.

2. What are the symptoms of a P0135 code in a 2017 Honda CR-V?

Common symptoms include an illuminated check engine light, reduced fuel efficiency, rough idling, and potential emissions test failure.

3. What causes the P0135 code to appear in a 2017 Honda CR-V?

Possible causes include a faulty air/fuel ratio sensor, a blown fuse, damaged wiring or connectors, or a malfunctioning engine control module (ECM).

4. Can I drive my 2017 Honda CR-V with a P0135 code?

While the car may still be drivable, itâ€™s not recommended as it can lead to poor fuel economy, higher emissions, and potential damage to other components.

5. How do I diagnose the P0135 code on a 2017 Honda CR-V?

Diagnosis involves checking the sensorâ€™s wiring and connectors, testing the heater circuit for continuity, and verifying the fuse and ECM functionality.

6. How do I fix the P0135 code on a 2017 Honda CR-V?

Common fixes include replacing the air/fuel ratio sensor, repairing or replacing damaged wiring, and checking or replacing any blown fuses.

7. How much does it cost to fix a P0135 code on a 2017 Honda CR-V?

Repair costs can vary, but replacing the air/fuel ratio sensor typically ranges from $150 to $400, including parts and labor.

8. Can a P0135 code cause long-term damage to my 2017 Honda CR-V?

If left unresolved, it can cause increased wear on the catalytic converter and lead to reduced engine performance over time.

9. How do I reset the P0135 code after fixing the issue on my 2017 Honda CR-V?

You can reset the code using an OBDII scanner or by disconnecting the battery for a few minutes, but ensure the issue is fully resolved first.

10. Is the P0135 code the same as an oxygen sensor malfunction?

Not exactly. P0135 specifically refers to the heater circuit of the Air/Fuel Ratio Sensor 1, which is a type of oxygen sensor but focuses on the heater functionality.
