A-Premium O2 Oxygen Sensor 4-Wire Heated Replacement for Jeep Dodge Chrysler Ram — 350mm Female Connector

A-Premium O2 Oxygen Sensor is a direct-fit, 4-wire heated replacement sensor engineered to restore accurate exhaust oxygen readings for compatible Jeep, Dodge, Chrysler, Ram, Fiat, Mitsubishi, Volkswagen and select Mercedes-Benz models.

This replacement oxygen (O2) sensor from A-Premium is designed to match factory fit and function for a wide range of vehicles. It uses a 4-wire heated design for faster warm-up and consistent voltage signals to the engine control unit (ECU). The sensor arrives boxed with a female connector and 350 mm overall length, making it suitable for many common downstream and upstream mounting locations listed by vehicle and reference number.

Which vehicles will this A-Premium O2 sensor fit?

The sensor fits numerous Chrysler, Dodge, Jeep, Ram, Fiat, Mitsubishi, Volkswagen and Mercedes-Benz models across multiple years. Fitment includes popular platforms such as Grand Cherokee, Wrangler, Charger, Challenger, Ram trucks, Pacifica and select Mercedes S/CLS/GL/GLE variants—verify your exact engine and OE reference number to be certain.

• Chrysler: 200, 300, Pacifica, Town & Country, Voyager, etc.
• Dodge: Avenger, Challenger, Charger, Durango, Grand Caravan, Journey, Viper, etc.
• Jeep/Ram/FIAT/Mercedes: Extensive coverage—see product reference numbers 250-24680, 25024680, 5149180AA, 7B0906262B for exact matches.

How does the 4-wire heated design benefit performance?

The four-wire heated O2 sensor contains an internal heater circuit that brings the sensing element to operating temperature quickly, improving response during cold starts. Faster warm-up helps the ECU adjust air-fuel ratio sooner, which supports smoother idle and better throttle response under varying conditions.

• Heated element reduces warm-up time compared with unheated sensors.
• Four-wire configuration separates heater power from signal and ground for reliable readings.
• Improves ECU control during drive cycles and transient conditions.

What are the sensor's physical and electrical specifications?

This A-Premium unit is a threaded, heated oxygen sensor with a female connector and four conductors. The overall harness length is 350 mm, and the package includes one boxed sensor ready for installation. It replicates OEM sensor mounting and electrical interface to simplify replacement.

• Wire quantity: 4 (heated signal + ground + heater power/ground).
• Overall length: 350 mm; Mounting: threaded style typical of factory ports.
• Connector gender: female; Package: 1x oxygen sensor in a protective box.

Will this sensor trigger a check engine light or require ECU coding?

When chosen to match your vehicle's OE reference or part number, this sensor replaces the factory unit without additional programming on most models. If the ECU has stored codes from a failed sensor, clearing the codes after installation lets the vehicle relearn signals during normal operation.

• Match reference numbers 250-24680, 25024680, 5149180AA or 7B0906262B where applicable.
• Clear any stored diagnostic codes after installation if necessary.
• No special adaptation generally required for direct-fit replacement on supported cars.

Who is this for: This A-Premium O2 oxygen sensor suits DIY mechanics, independent shops and fleet managers who need a reliable, direct-fit replacement for affected Chrysler, Dodge, Jeep, Ram, Fiat, Mitsubishi, Volkswagen and select Mercedes-Benz models. Choose this sensor if you require a heated, 4-wire assembly with standard threaded mounting and a 350 mm harness length that aligns with the listed reference numbers and model years.
