Steps to replace the battery in a Peugeot 308 key: First, remove the key ring. You can use a 1-yuan coin to wedge into a groove on the key, then apply some force to twist the coin and open it. After opening, take out the old battery and replace it with a new one, making sure to distinguish the positive and negative poles - positive pole down and negative pole up. The Peugeot 308 is a compact family car under the Peugeot brand, with a wheelbase of 2675mm. It comes equipped with three engines: a low-power version 1.2T turbocharged engine, a high-power version 1.2T turbocharged engine, and a 1.6L naturally aspirated engine. The low-power version engine has a maximum power of 85kW and a maximum torque of 190Nm, while the high-power version engine has a maximum power of 100kW and a maximum torque of 230Nm.

I've changed the battery for my Peugeot 308 key several times, and it feels quite straightforward. There's a small button on the side of the key; press it to pop out the small blade, and the key casing opens. Use a fingernail or a small flat-head screwdriver to gently pry open the shell—be careful not to break it. Inside, there's a CR2032 coin cell battery; make sure the positive side faces up to avoid incorrect installation. Remove the old battery, replace it with a new one, and then press the shell back together. After replacement, test the remote unlock and lock functions to ensure everything works. The battery typically lasts about two years. If the key acts up in winter or stops responding, it might be due to a drained battery. Don't skimp on quality when buying batteries—choose reputable brands to avoid frequent replacements. Doing it yourself saves a trip to the repair shop, saving time and money while learning a new skill. Remember to avoid using excessive force throughout the process to prevent damaging the key components.

Changing the battery in my Peugeot 308 key is quite straightforward. First, locate the small button on the side of the key and press it to release the blade part. The key casing can then be pried open—I usually use a small coin or my fingernail. Inside, the battery is a CR2032 model. Carefully remove the old battery, being cautious not to damage anything. Install the new battery, ensuring the positive side faces up, then snap the casing back together. Test the remote to confirm that locking and unlocking work properly. The battery typically lasts about two years, so when the key starts malfunctioning, it's time for a replacement. The process is simple and takes just a few minutes, saving you a trip to the shop and unnecessary expenses. Regular maintenance can also extend the key's lifespan—after replacing the battery, clean it to prevent dust from causing issues. Don't forget to wash your hands to remove static electricity and avoid short circuits. Beginners might need a few tries to get the hang of it.

Clean the three-way catalytic converter. Once this component is clogged or too dirty, it will lose its ability to convert carbon monoxide. Check the dashboard for any engine warning lights. If the air-fuel ratio of the engine cannot stabilize, incomplete combustion may occur.

What is the voltage of the ABS sensor connector?

The voltage of the ABS sensor connector is 5V to 8V, with an output voltage of 650mV to 850mV. During actual measurement, due to the fault protection function of the electronic stability control module, the voltage cannot be sustained after unplugging the ABS sensor connector, so voltage data cannot be used as a judgment criterion. The ABS sensor is an important component of the ABS system. ABS can maintain the directional stability of the vehicle during braking while driving, shorten the braking time and distance, and effectively prevent wheel lock-up and uncontrolled skidding during emergency braking, thereby enhancing the vehicle's controllability and making driving safer.
