Engine oil pressure sender / switch
Mounted on the cylinder head, this component monitors pressure within the engine lubrication system and supplies the corresponding signal for the dashboard oil-pressure display and warning system.
Fits:
Porsche 996 Carrera 3.4L / 3.6L 1998 - 2005
Porsche 997 Carrera 3.6L / 3.8L 2005 - 2008
Diagram Ref No 32. (Cylinder Head)
Functions
- Monitors engine oil pressure
- Provides information to the dashboard pressure gauge
- Supports the low oil-pressure warning system
- Helps identify potentially unsafe lubrication conditions
Technical Details
- Brand: OE Match
- Porsche cross-reference: 99660620303
- Installation position: cylinder head
- Diagram location: cylinder head, reference number 32
Symptoms of Fault
- Oil-pressure gauge readings that fluctuate unexpectedly
- Gauge momentarily dropping to zero before recovering
- Warning light flickering at idle despite the correct oil level
- Pressure display remaining unusually high or low
- Intermittent readings associated with heat or vibration
- Oil seepage around the sender body or connection
Why Replacement Matters
A defective sender may produce inaccurate readings or false dashboard warnings. However, low oil pressure can also indicate a genuine lubrication fault, so the engine oil level and actual pressure should be checked before the sender is assumed to be the cause. A mechanical pressure test is the preferred method of confirming the engine's true oil pressure.
FAQs
- Does a flickering oil warning always mean the sender has failed?
No. Treat any oil-pressure warning as genuine until the oil level and actual pressure have been checked. - How can the sender be diagnosed?
Inspect the electrical connection and wiring, then compare the displayed reading with a mechanical oil-pressure gauge. - Should a leaking sender be replaced?
Yes. Seepage from the sender body or seal can worsen and allow oil to contaminate nearby components.

This OE Match oil pressure sensor / switch is mounts at the oil filter housing and replaces the earlier Porsche references 99660620300 and 99660620301.
Fits:
Porsche 996 Turbo 2001 – 2005
Porsche 996 GT3 / GT3 RS 2001 – 2005
Diagram ref no 45
What This Product Does
The sender monitors pressure within the engine lubrication system and provides the electrical signal used by the vehicle's oil-pressure display and warning system. Correct sender operation allows the driver to identify a potential pressure problem without misleading or intermittent readings from a defective component.
Functions
- Monitors engine oil pressure
- Provides an electrical signal for the dashboard display
- Supports operation of the oil-pressure warning system
- Replaces a leaking, damaged or unreliable sender
Technical Details
- Brand: OE Match
- Mounting position: oil filter housing
- Reference number: 99660620302
- Supersedes: 99660620300 and 99660620301
- Parts diagram reference: 45
Symptoms of Fault
- Oil-pressure gauge readings fluctuate unexpectedly
- Gauge briefly falls to zero and then recovers
- Oil warning light flickers despite the correct oil level
- Pressure reading remains unusually high or low
- Intermittent readings occur as the engine warms up
- Oil seepage is visible around the sender body or connection
Why Replacement Matters
A faulty sender can imitate a serious lubrication-system problem or prevent the dashboard from displaying reliable information. Actual low oil pressure can cause significant engine damage, so warning lights or abnormal readings should be treated seriously. Check the oil level and condition first, then verify the engine's true oil pressure with suitable test equipment before assuming that the sender is the only fault.
OE Reference
- 99660620302
- 99660620300
- 99660620301
FAQs
- Can a defective sender cause a false oil-pressure warning?
Yes. Electrical wear, internal failure or a poor connection can produce intermittent or inaccurate readings, although genuine pressure loss must be ruled out first. - How should an abnormal reading be checked?
Confirm the oil level and inspect for leaks. A mechanical pressure-gauge test can then be used to establish the engine's actual oil pressure. - Where is this sender installed?
It is fitted at the oil filter housing on the listed 996 Turbo and GT3 applications. - Does it replace earlier Porsche part numbers?
Yes. Reference 99660620302 supersedes 99660620300 and 99660620301.

OEMatch Oil Pressure Senders / Switches — Durability, Sealing, Performance
Keep accurate engine oil pressure information for Porsche models with pressure senders and warning switches selected for reliable, consistent signalling. These units convert mechanical pressure into dashboard readings or warning alerts, helping to indicate lubrication issues early and supporting correct engine operation and maintenance decisions.
Available Types- Pressure sender for gauge circuits
- Pressure switch for dashboard warning lights
- Combined sender/switch units where fitted
- High-pressure and low-pressure variants for specific engines
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil pressure senders / switches.
OE (Original Equipment) refers to parts matching original specifications for the oil pressure senders / switches and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil pressure senders / switches engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Oil pressure senders and switches monitor the lubrication system and provide either continuous pressure readings or a threshold warning. A sender produces a variable signal for the gauge while a switch operates a warning lamp at low pressure. Faulty units can give flickering or incorrect readings, false warnings, or fail to alert when pressure drops. OEMatch maintains a wide catalogue of Porsche part numbers and numerous OE cross-references and continues to develop new product lines to support maintenance and restoration.
- Restores accurate oil pressure signalling to the instrument panel
- Reduces false low-pressure warnings that can cause unnecessary intervention
- Helps maintain correct engine lubrication awareness for routine checks and servicing
- Oil contamination or sludge blocking internal ports and diaphragms
- Electrical corrosion, degraded connectors or wiring faults
- Seal deterioration, thread damage or oil leaks at the mounting point
- Thermal cycling and vibration leading to sensor drift or mechanical fatigue
Accurate oil pressure information is essential for safe and reliable engine operation. A dependable sender or switch reduces the risk of unnoticed low oil pressure and the subsequent wear that can accelerate bearing and component damage. Replacing a degraded unit restores clear dashboard indication and supports correct maintenance decisions for Porsche engines.
Advantages- Direct-fit replacements engineered to match original dimensions and tolerances
- Constructed from heat- and corrosion-resistant materials for long service life
- Designed to mate with original electrical connectors and mounting points for straightforward installation
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
