Ordering a replacement sensor by vehicle name alone can create an expensive mismatch. For a Volvo S40 A/C pressure sensor 31332642, the most reliable starting point is the number printed or molded on the original part. The NexuParts listing references OE/OEM numbers 31332642 and 30730516, but the connector, pin arrangement, mounting style, and overall appearance should also match before the replacement is installed.
The 31332642 / 30730516 A/C refrigerant pressure sensor for Volvo S40 is active and in stock. Its vehicle reference helps narrow the search, but it is not a substitute for checking the original component. Model names, production markets, trims, engines, and connector designs can vary, so use several pieces of evidence together.
What the 31332642 and 30730516 Numbers Tell You
OE and OEM reference numbers help distinguish parts that may share a similar shape or function. On this listing, 31332642 is also the SKU, while 30730516 is an additional reference number. Either number may help you locate a candidate replacement, but the number on your original part should control the comparison.
Read every character carefully. A shortened number, a missing digit, or a marketplace title that only says “Volvo pressure sensor” is not enough. If the original number is unreadable, take clear photos of the label, connector, pins, mounting area, and complete housing before requesting fitment help.
How to Verify a Volvo S40 A/C Pressure Sensor 31332642
1. Match the original OE/OEM number
Look for 31332642 or 30730516 on the removed sensor, its label, or a reliable vehicle-specific parts record. Compare the full number rather than relying on a partial match. If your original part shows a different number, do not assume that a similar-looking sensor is interchangeable.
2. Compare the connector shape and keying
View the original connector and the product photos from the same angle. Check the outer shape, locking tab, keying, pin count, and the arrangement of occupied and empty positions. A plug can appear almost identical and still use different keying or internal connections.
3. Check the mounting or insert style
Compare how the sensor meets the vehicle system. Review the mounting surface, tabs, retaining features, thread or insert style, and the shape around the base. Do not force a part into place or modify the housing simply because the connector appears to fit.
4. Compare the complete housing
Place the original part beside the product images and compare overall length, body diameter, molded contours, orientation, and any alignment features. Product photos are most useful when you compare one detail at a time instead of relying on a general visual impression.
5. Confirm the vehicle details as supporting evidence
Record the vehicle year, Volvo make, S40 model, engine, trim, and market. These details support the decision, but they should not override a conflicting OE number or physical mismatch. If the listing title agrees with the vehicle but the connector or mounting style differs, stop and verify before ordering.
Why Symptoms Alone Cannot Confirm the Part
A diagnostic code, warning message, or climate-control complaint may lead you to inspect an A/C pressure sensor, but it does not prove that this specific replacement is correct. Wiring, connectors, refrigerant-system conditions, and other electrical or mechanical components can produce overlapping results. Diagnosis should identify the failed component before fitment verification begins.
This distinction matters because two separate questions must be answered: “Is the sensor the failed component?” and “Is 31332642 or 30730516 the correct replacement?” A symptom may help with the first question, while the OE number and physical comparison answer the second.
Buying Checklist Before You Order
- Confirm the original part or reliable record shows 31332642 or 30730516.
- Compare connector outline, keying, locking feature, and pin arrangement.
- Check mounting points, thread or insert style, and retaining features.
- Compare overall housing shape, length, base, and orientation.
- Record the vehicle year, make, model, engine, trim, and market.
- Use the actual installation location as part of the comparison.
- Resolve any difference before ordering or installation.
You can browse the NexuParts Lighting & Electrical collection for other model-specific sensors and electrical replacements. Products within the same category are not automatically interchangeable; each listing must be checked against its own OE number and physical configuration.
How a Related Sensor Listing Helps with Comparison
The BR1A-66-490 / 8T4T-96854-M Ford and Volvo sensor listing is another active electrical-sensor product, but it has a different function, OE reference, and application. It is useful as an example of why “Volvo sensor” is too broad a shopping phrase. The correct category or brand does not make one sensor a substitute for another.
Keep every OE number tied to its own product page. For the A/C refrigerant pressure sensor in this guide, the relevant references are 31332642 and 30730516. For a different sensor, start the verification process again instead of carrying over assumptions.
What to Check Before Installation
Before installation, compare the new and original sensors side by side. Confirm the connector locks in the same direction, the pins and keying agree, and the mounting or insert style matches without force. Inspect the new part for shipping damage and keep the connector and housing unmodified while the comparison is completed.
The product listing recommends professional installation. Electrical parts, sensors, switches, and modules that have been installed, modified, damaged, or show signs of use may have different return eligibility unless they are defective or incorrectly shipped. Completing the comparison before installation protects both the vehicle and the purchase.
Frequently Asked Questions
Will 31332642 fit every Volvo S40?
No universal fitment should be assumed from the model name alone. Match OE/OEM number 31332642 or 30730516, then compare the connector, pins, mounting style, housing, installation location, and vehicle details.
Is 30730516 the same as 31332642?
The NexuParts product page lists both as OE/OEM references for the same replacement listing. Your original part number and physical details still need to agree before purchase.
What if my connector looks similar but the pin layout differs?
Treat that as a mismatch until verified. Do not modify the connector or wiring to make a questionable sensor fit. Send clear photos and the vehicle information for comparison.
Can NexuParts help check fitment?
Yes. Send the VIN, original OE/OEM number, vehicle year, make, model, engine, the product link, and clear photos of the original part and connector to info@NexuParts.com before ordering.
What comes with the product?
The listing states that the package includes one A/C refrigerant pressure sensor. Confirm the required quantity and installation location before purchase.
Choose the 31332642 Replacement with Evidence
A Volvo S40 A/C pressure sensor 31332642 should be selected through a complete evidence check: OE/OEM number, connector, pins, mounting style, housing, installation location, and vehicle details. When every point agrees, the purchase decision is based on the original part rather than a generic search result. Review the NexuParts 31332642 / 30730516 sensor listing and request fitment help before ordering if any detail remains uncertain.
