The sensors on the Chery Tiggo 3 are located on the exhaust pipe, front wheel brake discs, and near the throttle. Below is an introduction to the sensors on the Chery Tiggo 3:1. Oxygen sensor: The oxygen sensor is installed on the exhaust pipe to monitor the post-combustion gases and determine whether the engine is burning fuel efficiently.2. Wheel speed sensor: The wheel speed sensor is usually located on the front wheel brake discs. Its main function is to collect the vehicle's speed to detect any signs of wheel slippage.3. Water temperature sensor: The water temperature sensor is typically installed near the thermostat, converting the coolant temperature into an electrical signal.4. Intake pressure sensor: Generally installed near the throttle, the intake pressure sensor, as the name suggests, senses a series of resistance and pressure changes as the engine's speed and load vary, converting these into voltage signals for the ECU to adjust fuel injection and ignition timing.

The sensor distribution on the Tiggo 3 is quite extensive, and I often deal with them during car repairs. In the engine section, there's the intake pressure sensor on the intake manifold, and the crankshaft position sensor is usually hidden under the front cover. The exhaust pipe is equipped with front and rear oxygen sensors, with the front one located near the engine exhaust port. In the cooling system, the water temperature sensor is typically installed on the radiator or thermostat housing. As for the chassis, the wheel speed sensors are mounted next to the brake discs, one for each wheel. The air conditioning system also has temperature sensors near the air vents. My advice is not to rush into replacing parts when encountering a fault; first, use a diagnostic tool to read the data stream and pinpoint the issue.

Sensor locations vary by function: For fuel consumption control, components like the mass airflow sensor sit behind the intake pipe. In the powertrain, knock sensors are mounted mid-block, while transmission fluid temperature sensors typically embed near the valve body. Safety systems are equally precise—ABS wheel speed sensors attach adjacent to hub bearings, and airbag crash sensors fix securely inside B-pillars. When diagnosing illuminated warning lights, I always prioritize electrical connector inspections. The wiring routing on Tiggo 3 models occasionally causes intermittent connection issues at junctions.

The sensor layout of this car is quite reasonable. Under the hood, you can see the intake air temperature sensor behind the air filter box, and the oil pressure sensor screwed near the oil pan. For the emission system, there are front and rear oxygen sensors spaced out in the exhaust. The most frequently serviced sensor on the chassis is the steering angle sensor, which is installed inside the steering column assembly. The air conditioning pressure sensor is attached to the high-pressure pipeline. I've seen novices mistake the tire pressure monitoring module for a sensor, but the actual sensor is hidden inside the wheel hub using magnetic induction. During regular , blow away the dust in the engine compartment to prevent sensor connectors from getting clogged with oil sludge.

Sensors are concentrated in several key areas: the outside temperature sensor in the cabin is located inside the front bumper grille; for body control, the sunlight sensor is embedded in the small dot on the dashboard near the windshield. The engine compartment has the most temperature-related sensors, with an exhaust temperature sensor even hidden near the turbocharger. Once, while troubleshooting an engine error, I found the crankshaft position sensor damaged by leaking oil. Such faults require quick repairs, and special attention should be paid to protecting lower-positioned sensors from scrapes and impacts.

From a safety perspective, key sensor locations: Wheel speed sensors are mounted on the hub to protect the braking system, while airbag sensors are positioned between doors and seats. For the powertrain, the crankshaft position sensor sits near the pulley to control ignition timing; knock sensors monitor vibrations on cylinder sides. Refrigeration system pressure sensors are strapped to high/low pressure lines. I've found sensor connector oxidation to be a common issue, especially for units mounted beneath the engine prone to corrosion. During DIY inspections, pay extra attention to sensor housings as certain plastic components are particularly fragile.
