Code C1271 2017 Toyota RAV4 Description
The C1271 diagnostic trouble code (DTC) for a 2017 Toyota RAV4 indicates a low output signal from the front right speed sensor. The speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. It is responsible for measuring the speed of the front right wheel and sending this information to the ABS control module. This data is used to determine wheel speed discrepancies and adjust braking pressure accordingly to prevent wheel lock-up during braking or loss of traction.
Common Causes of C1271 2017 Toyota RAV4
- Faulty front right speed sensor
- Damaged or corroded wiring/connectors leading to the speed sensor
- Contaminated or worn-out speed sensor reluctor ring
- Issues with the ABS control module
- Electrical problems within the ABS system
Symptoms of C1271 2017 Toyota RAV4
- ABS warning light illuminated on the dashboard
- Erratic or pulsating brake pedal during braking
- Increased stopping distances
- Traction control system engaging unexpectedly
- Loss of traction on slippery surfaces
How to Fix C1271 2017 Toyota RAV4
- Begin by visually inspecting the front right speed sensor and its wiring for any visible damage or corrosion.
- Use a multimeter to test the output signal of the speed sensor and compare it to manufacturer specifications.
- If the sensor is faulty, replace it with a new OEM (original equipment manufacturer) speed sensor.
- Check and clean the speed sensor reluctor ring to ensure proper operation.
- Clear the DTC from the ABS control module using a diagnostic scan tool and perform a road test to verify that the issue has been resolved.
Cost to Fix C1271 2017 Toyota RAV4
The cost of repairing a low output signal from the front right speed sensor on a 2017 Toyota RAV4 can vary depending on the specific cause of the issue and the labor rates in your area. In general, the price of a new OEM speed sensor ranges from $50 to $150, while labor costs can range from $100 to $300. Therefore, the total repair cost could be anywhere from $150 to $450.

Tech Notes for C1271 2017 Toyota RAV4
If there is iron powder sticking to the rotor, this will result in a malfunction, so confirm that the rotor is not contaminated with foreign material before replacing the sensor.
Check the speed sensor signal after cleaning or replacement.
On most vehicles, the Front Speed Sensor Rotor is incorporated into the Front Axle Hub Sub-Assembly. If the Speed Sensor Rotor needs to be replaced, replace it together with the Front Axle Hub Sub-Assembly.
