Source Opel Astra Crankshaft Position Sensor for Engine Repair

Opel Astra Crankshaft Position Sensor Sourcing Guide

Procuring the correct crankshaft position sensor for an Opel Astra requires precise alignment with the vehicle's specific engine management system. The available market listings indicate a strong focus on digital output signal types designed specifically for gas measurement applications within the automotive electrical system. Buyers must verify that the selected unit matches the exact OE number, such as 021907319b or 9118150, to ensure seamless integration with the engine control unit.

The product scope extends beyond simple replacement to include universal fitment options for various Opel models, including Holden and Suzuki variants. Listings confirm that these sensors are typically supplied as new units with a condition verified through professional testing protocols. Sourcing strategies should prioritize suppliers offering customization options and multiple packaging types, ranging from OEM to neutral packages, to accommodate different logistical and branding requirements for fleet maintenance or retail distribution.

Product Scope and Observed Listing Signals

Market analysis reveals a diverse range of model numbers associated with this component, including 96389566, 949979130, and 28129701, which suggests significant variation in manufacturing origins and specific engine compatibility. Buyers should observe that while the core function remains consistent, the physical dimensions and packaging standards vary, with some units listed at 12CM by 6.5CM by 4.5CM and others at 13 by 8 by 6 cm. This variance necessitates careful cross-referencing of the single package size against the vehicle's physical mounting constraints before finalizing any purchase order.

Listing signals also highlight the availability of specific brand names like Cowtotal and Credit Parts, indicating a competitive landscape with multiple manufacturers supplying compatible parts. The observed data confirms that these products are generally sourced from Guangdong, China, with delivery times ranging from 3 to 10 working days depending on the specific supplier's logistics capabilities. Procurement teams must account for these lead time variations when planning inventory replenishment to avoid production delays in vehicle repair operations.

Technical Specifications to Verify

Technical verification begins with confirming the output signal type, as the supplied facts explicitly identify these units as digital type sensors essential for accurate engine timing data. The sensor must be compatible with the specific gas measurement requirements of the Opel Astra's engine management system, ensuring that the electrical interface matches the vehicle's wiring harness without requiring modification. Buyers should request detailed datasheets that confirm the sensor's ability to operate within the standard voltage ranges expected by the automotive electrical system.

Physical specifications are equally critical, with model numbers like 90919-05005 and 90506103 representing distinct dimensional profiles that must match the original equipment. The single gross weight of these units typically ranges from 0.200 kg to 0.300 kg, which influences shipping costs and handling procedures for bulk orders. Verification of the standard size, often described as OEM standard size, ensures that the replacement part will fit the designated mounting location without interference from surrounding engine components.

Compliance and Safety Documentation

While specific certification documents are not explicitly detailed in the provided listings, the consistent mention of "100% Professional Test" and "100% tested" quality attributes suggests a baseline commitment to functional safety and reliability. Buyers should request formal test reports that validate the sensor's performance under various operating conditions, ensuring it meets the rigorous safety standards required for critical engine management components. This documentation is essential for maintaining liability coverage and ensuring that the installed parts do not pose a risk to vehicle operation.

The origin of the products, primarily from China (Mainland), requires buyers to verify that the manufacturing processes adhere to international automotive quality standards. Although specific certification bodies are not named in the source data, the presence of a one-year or 12-month warranty indicates a manufacturer's confidence in the product's durability and safety. Procurement teams must ensure that the supplier can provide traceability records for the raw materials used, particularly the plastic housing, to confirm compliance with environmental and safety regulations.

Cost Drivers and Commercial Terms

The pricing structure for these sensors is influenced by the complexity of the digital signal processing and the specific OE number compatibility required for the Opel Astra. Observed price ranges in the market span from 1 to 99 USD, reflecting differences in brand reputation, packaging customization, and the specific model number being supplied. Buyers should analyze the cost per unit against the warranty terms, as higher-priced items often include more comprehensive testing and longer support periods, which can reduce long-term maintenance costs.

Commercial terms are a significant factor in the total cost of ownership, with payment methods including T/T with a 30% deposit, Western Union, and PayPal. The minimum order quantity (MOQ) varies between 1 and 100 units, allowing flexibility for both small repair shops and large fleet operators. Lead times of 3 to 7 days or 3 to 10 working days must be factored into the budget planning, as expedited shipping options like DHL, FedEx, and UPS will incur additional costs that impact the overall procurement budget.

Supplier Qualification and Quality Control

Supplier qualification should prioritize vendors who explicitly state a "100% Professional Test" protocol and offer a warranty of at least one year. The presence of multiple packaging options, such as OEM, neutral, and Al Lamp packages, indicates a supplier's ability to adapt to different client needs, which is a strong indicator of operational maturity. Buyers must verify that the supplier has a consistent track record of delivering new condition parts that match the specified model numbers and OE numbers without deviation.

Quality control processes must be validated through the supplier's ability to provide detailed inspection reports for each batch of sensors. The observation that products are tested for the automotive electrical system application suggests that functional testing is a standard part of the production workflow. Procurement teams should request samples for independent verification to ensure that the digital output signal and physical dimensions match the specifications before committing to a large-scale order.

Long-Term Procurement Checks

Establishing a long-term relationship with a supplier requires regular audits of their quality control processes and adherence to the specified delivery times. Buyers should monitor the consistency of the model numbers and OE numbers supplied over time to ensure that the components remain compatible with the Opel Astra fleet. Regular performance reviews should include checking the warranty claim rates to identify any potential issues with the sensor's durability or signal accuracy.

Continuous improvement in the procurement process involves staying updated on new model numbers and OE standards that may emerge for the Opel Astra. The availability of customization options suggests that suppliers are willing to adapt to changing requirements, which is vital for maintaining a resilient supply chain. Buyers should maintain open communication channels with suppliers to discuss potential design changes or updates that could affect the compatibility and performance of the crankshaft position sensors in future orders.
