Crankshaft Position Sensor For ISUZU NKR NPR NQR TFR TFS 8973066010 8973235540 8972400340 0281002553 4JH1 4KH1 Crank Angle Sensor

The Crankshaft Position Sensor (also known as Crank Angle Sensor or CKP Sensor) is a critical engine management component for ISUZU diesel engines. It monitors the rotational speed and position of the crankshaft, sending this vital data to the Engine Control Unit (ECU). The ECU uses this signal to precisely control fuel injection timing and ignition timing.

When this sensor fails, your engine may experience hard starting, rough idling, sudden stalling, or complete failure to start . For ISUZU 4JH1 and 4KH1 engines found in NKR, NPR, NQR, TFR, and TFS models, a reliable crankshaft position sensor is essential for maintaining optimal engine performance and fuel efficiency.

Designed to withstand extreme temperatures, vibration, and harsh under-hood conditions, this sensor provides accurate crank angle detection to ensure your engine runs smoothly mile after mile.

Q1: What is the difference between the three quality levels?

Quality Level	Key Differences
Aftermarket Quality	Standard-grade components – economical choice for basic replacement
Famous Brand BOSCH Quality	Premium Tier 1 supplier – enhanced durability and signal accuracy – best for professional use
Japan ISUZU Quality	Factory original grade – meets ISUZU's strict quality standards – maximum longevity

Q2: What does a crankshaft position sensor do?

A: It monitors the crankshaft's rotational speed and position, sending this data to the ECU. The ECU uses this information to precisely time fuel injection and engine ignition . Without this signal, modern diesel engines will not start or run properly .

Q3: Is BOSCH quality better than Japan ISUZU Quality?

A: Both are premium options. Japan ISUZU Quality is the genuine factory standard, identical to what came with your truck from the factory. BOSCH Famous Brand Quality is a premium aftermarket option from a world-leading automotive supplier. Both offer excellent reliability – choose based on your brand preference.

Q4: Will this fit my ISUZU engine?

A: This sensor is designed specifically for ISUZU 4JH1 and 4KH1 engines found in NKR, NPR, NQR, TFR, and TFS models. Please confirm your OE number matches one of the listed numbers: 8973066010, 8973066011, 8973235540, 8972400340, or 0281002553.

Q5: My engine won't start – is it definitely the sensor?

A: While a failed crankshaft position sensor is a common cause of no-start conditions, you should also check wiring connections, battery voltage, and fuel supply. We recommend proper diagnostic testing before purchasing replacement parts .

Q6: Do you offer wholesale pricing for bulk orders?

A: Yes. Please contact us with your quantity and preferred quality level for a competitive quote.

Q7: What is your warranty policy?

A: This product comes with a 1-year warranty against manufacturing defects. Please contact our support team for any issues.

Q8: Can I get custom branding or packaging?

A: Yes. Custom packing with your logo or specifications is available for bulk orders.
