5408505100201 Throttle Body is an electronically controlled intake adjustment assembly mounted on the intake pipeline of JAC QC4A2 diesel engine. It receives real-time ECU signals to adjust the opening angle of internal butterfly flap, precisely regulating intake airflow and cooperating with DPF aftertreatment system to complete regeneration and stabilize idle speed. This aftermarket throttle body solves unstable idle, weak acceleration response and frequent emission fault codes caused by carbon accumulation on valve plate, actuator jamming and position sensor signal drift after long-term operation in dusty working environments. Reliable air flow regulation prevents engine derating and keeps exhaust emission within standard range for JAC light trucks and logistics vans used for urban distribution and short-distance suburban freight.
Product Advantages Made of die-cast aluminum alloy housing with anti-corrosion surface treatment. Built-in electric actuator delivers fast and stable flap response; integrated position sensor feeds accurate angle data back to ECU continuously. The valve flap adopts anti-carbon coating to reduce carbon deposit adhesion. Each throttle body undergoes electrical function test and air tightness inspection before delivery, OEM mounting hole layout and connector pin definition for direct replacement.

FAQ
Q1: What typical symptoms indicate a faulty throttle body?
A1: Fluctuating idle speed, slow throttle response and recurring OBD trouble codes related to intake system.
Q2: Can carbon cleaning fix all throttle body failures?
A2: Cleaning only removes carbon deposits. If the drive motor or internal sensor is damaged, replacement is required.
Q3: What mandatory operation should be finished after new throttle body installation?
A3: Perform ECU throttle adaptive learning to calibrate the baseline position of the valve flap.
Q4: How to extend the service life of this throttle body?
A4: Replace air filter regularly to reduce dust entering the intake pipeline and slow carbon buildup.
