8121468300 Air Intake Temperature Sensor For Excavator Engine 4HK1 6HK1 8-12146830-0

Product Details

Product Overview

This genuine Air Intake Temperature Sensor, identified by part number 8121468300 (also known as 8-12146830-0), is a critical component designed specifically for diesel engines in heavy-duty excavator applications. Manufactured to original equipment specifications in Japan, this sensor provides accurate intake air temperature readings to the engine control unit (ECU), ensuring optimal fuel injection timing and combustion efficiency.

While commonly associated with the Isuzu 4HK1 and 6HK1 engine families, this sensor is widely utilized in various excavator models from leading construction equipment manufacturers. It serves as a direct replacement for the OEM part, offering the same reliability and performance as the original component.

For B2B buyers, this sensor represents a high-demand service part for fleet maintenance and repair operations. Its precision engineering ensures consistent engine performance, reduced emissions, and protection against overheating-related damage.

Key Features & Benefits

FAQ

Q1: How do I confirm if this sensor fits my specific excavator model?
A: First, locate the part number on your existing sensor (typically stamped on the sensor body or connector housing). If it matches 8121468300 or 8-12146830-0, it is a direct replacement. Additionally, verify that your equipment uses an Isuzu 4HK1 or 6HK1 engine. If you are unsure, please provide your machine’s model and serial number, and our technical team can assist with cross-referencing.

Q2: What are the symptoms of a failing air intake temperature sensor?
A: Common signs include: check engine light illumination, poor fuel economy, rough idling, black smoke from exhaust, reduced engine power, and difficulty starting in cold conditions. The sensor may also cause incorrect EGR system operation. If you experience these issues, testing the sensor’s resistance with a multimeter (compared to manufacturer specifications) can confirm if replacement is needed.

Q3: Is installation difficult, and what tools are required?
A: Installation is straightforward for a qualified mechanic. The sensor is typically located in the intake manifold or air intake pipe. Basic hand tools (socket wrench, screwdriver) are usually sufficient. Always disconnect the battery before working on electrical components. Apply anti-seize compound to the sensor threads if recommended by the manufacturer. After installation, clear any diagnostic trouble codes and perform a test drive to verify proper operation.
