Where are the sensors on a Toyota C-HR?

The C-HR’s sensors are mainly located in three areas: behind the front grille (radar), behind the windshield (camera), and in the bumpers (ultrasonic sensors). Depending on year and market, additional sensors for Blind Spot Monitor and rear cross-traffic alert may also be included.

Core sensing components in the C-HR

The vehicle’s safety systems rely on a combination of radar, camera, and ultrasonic sensors. The following components are commonly found across many C-HR models equipped with Toyota Safety Sense:

• Front millimeter-wave radar sensor located behind the front grille (center) for adaptive cruise control and pre-collision operations.


• Windshield-mounted monocular camera behind the rear-view mirror for lane-keeping assist, traffic sign recognition, and pedestrian detection.


• Ultrasonic parking sensors embedded in the front bumper to detect obstacles at low speeds during parking and maneuvering.


• Ultrasonic parking sensors embedded in the rear bumper to aid parking, with some markets enabling rear cross-traffic alert.


• Radar sensors used for Blind Spot Monitor positioned in the outer rear bumper corners or in the side mirror area, depending on the model year and market.

These sensors feed the car’s safety software, enabling features like adaptive cruise control, lane centering, collision avoidance, and parking assistance. If a sensor is blocked, dirty, or damaged, performance of the related systems can be affected.

Sensor placement by area

Front end

The primary front sensor is the millimeter-wave radar tucked behind the front grille, usually near the center. Some trims also include front ultrasonic sensors in the bumper to assist with close-range obstacle detection during parking and low-speed maneuvers.

Windshield and cabin area

The camera is mounted behind the windshield, near the top of the glass around the area of the rear-view mirror. This camera supports lane-keeping assist, traffic sign recognition, automatic high beams, and, in some markets, pedestrian detection. Availability of features tied to the camera can vary by trim and region.

Rear and sides

Rear ultrasonic sensors in the rear bumper support parking aids and, in some configurations, rear cross-traffic alert. Blind Spot Monitor sensors are typically located in the outer edges of the rear bumper or within the side mirror housing, depending on the model year and market. Some higher-end trims or regional packages may also offer a wider camera-based view (360-degree) in lieu of traditional sensor layouts.

Variations by year and market

Sensor configurations can vary depending on model year, trim level, and regional specification. The following are common differences you may encounter:

• Higher trims often include both front and rear parking sensors as standard; lower trims may omit front sensors.


• Blind Spot Monitor (BSM) availability and the exact sensor placement can differ by market and generation.


• Road Sign Assist, Lane Tracing Assist, and some features tied to the camera may require a particular Safety Sense version (for example, newer iterations like Safety Sense 2.0) and market.


• Some markets offer a 360-degree camera as an option or as part of a package on select trims; the standard view may differ by region.

Understanding your specific C-HR’s sensor layout will depend on the model year and the Safety Sense package installed by the manufacturer for your country.

Maintenance and care

Keeping sensors in good condition

Regularly inspect and clean sensors and cameras to prevent false alerts or degraded performance. Do not apply wax or coatings near sensor housings, and avoid mounting accessories or aftermarket parts that could obstruct or misalign sensors. If you notice warning lights or degraded system performance, have the vehicle inspected at an authorized Toyota service center.

Summary

In a Toyota C-HR, essential sensing components are the radar unit behind the front grille, the camera mounted behind the windshield, and bumper-embedded ultrasonic sensors for parking assistance. Depending on trim and market, Blind Spot Monitor and rear cross-traffic features rely on sensors located in the rear bumper corners or side areas, with potential variations including a 360-degree camera on certain models. Overall, the sensor layout supports a suite of safety features designed to help with braking, steering, visibility, and parking assistance.

Where is the PCS sensor on a Toyota C-HR?

The PCS malfunction indicator light indicates that the PCS sensor is probably dirty. The sensor is located behind the Toyota emblem at the front of the C-HR.

How to turn off car sensor Toyota?

Down until we see this icon that is your parking sensor icon. So um you can turn just hit one time on the Okay. And you say "I just shut it off." Right. But if you press and hold the okay. Button.

Why is Toyota discontinuing the C-HR?

The Toyota C-HR was discontinued in North America after the 2022 model year due to low sales compared to the more popular Corolla Cross, which offers a combination of utility and efficiency. Other factors contributing to its discontinuation included its small interior space, underpowered engine, and the fact that it was only available in front-wheel drive. The Corolla Cross was the more practical choice for buyers and has become the smallest crossover in Toyota's lineup.
 

• Lower sales: The C-HR never reached the sales figures of competing models, and even the Corolla Cross sold significantly more units when it was introduced. 
• Practicality issues: The C-HR's stylish, coupe-like design came at the cost of a cramped rear seat and limited cargo space. 
• Performance: The 2.0-liter four-cylinder engine with 144 horsepower was seen as underpowered, and it was only offered in a front-wheel-drive configuration, which was less appealing to consumers looking for more capability. 
• Internal competition: The Corolla Cross was a more practical and appealing option that cannibalized C-HR sales and offered all-wheel drive, which was a key feature for many buyers. 
• Product lineup evaluation: Toyota is constantly evaluating its product lineup, and the C-HR's discontinuation made way for other models like the Corolla Cross, which offered a better combination of utility and efficiency for the compact SUV segment. 

What is the common problem with Toyota C-HR?

Common problems reported for the Toyota C-HR include issues with the CVT transmission in earlier models (2018), problems with the 12-volt battery and charging system, electrical gremlins like faulty warning lights, and paint-related concerns. Other less frequent issues include blind spot limitations, infotainment system glitches, and potential wear on interior materials.

Powertrain and engine 

• CVT transmission: Some 2018 models have reported noisy, grinding, or humming sounds, potentially due to a faulty final drive bearing. The fix can be expensive, as it may require replacing the entire transmission unit. 
• 12-volt battery: The 12-volt battery can have issues, sometimes due to its small capacity and being drained by electronics. This can cause starting problems, even though it's not a major engine failure. 
• Engine: In some cases, the engine oil level may rise above the maximum mark, though this is reportedly not a safety issue. 

Electrical and electronic systems 

• TPMS sensors: A common issue is the failure of the Tire Pressure Monitoring System (TPMS) sensors. 
• Electrical gremlins: Other electrical problems can include faulty warning lights, general sensor malfunctions, and connectivity issues with the infotainment system. 
• Pre-Collision System (PCS): The warning light may activate frequently in rainy or snowy conditions, but the system usually resolves itself once it dries. 

Body and interior

• Paint: Some owners have reported issues with paint, especially on white models.
• Interior wear: The leather on the steering wheel, gear knob, and seats can show wear over time.
• Rear windows: Some 2020 models have experienced rear window cracking or shattering.
• Blind spot: Due to the design of the C-HR, visibility is limited, which can make lane changes challenging and create a blind spot. 

Suspension

• Shock absorbers: Early models sometimes had noisy shock absorbers. 
• Suspension components: Owners have reported premature wear on some suspension components.
