Cylinder head temperature sensor. Porsche 911 3.2L 1984-89 › 93060691500

OE Match cylinder head temperature sensor for Porsche 911 3.2L models from 1984–89. The sensor fits to the cylinder head and provides temperature information for engine management.

Fits

• Porsche 911 1984-89
• 911 1984–1986 3.2L
• 911 1987–1989 3.2L G50

Diagram Ref No 19

What This Product Does
The sensor measures cylinder-head temperature, giving the engine management system information about the engine's thermal condition. Temperature input helps the control system determine appropriate fuelling during starting, warm-up and normal running. This component measures cylinder-head temperature rather than engine oil temperature.

Functions

• Measures temperature at the cylinder head.
• Provides an electrical temperature signal to engine management.
• Supports temperature-dependent fuelling adjustments.

Technical Details

• Brand: OE Match.
• Supplied part reference: 93060691500.
• Installation position: cylinder head.
• 1984–86 diagram applications: engine codes 930.20/21/26.
• 1987–89 diagram applications: engine codes 930.20/25/26.

Symptoms of Fault

• Difficulty starting with a cold or hot engine.
• Uneven idle or irregular running.
• Higher fuel consumption associated with incorrect temperature input.
• Intermittent operation linked to heat, vibration or a damaged electrical connection.

These symptoms can also originate elsewhere. Inspect the connector, wiring and earth connections, and test the sensor before deciding that replacement is required.

Why Replacement Matters
A defective sensor can give engine management an inaccurate indication of temperature, affecting temperature-dependent fuelling. Replacing a confirmed faulty component addresses that signal fault; it will not correct damaged wiring or unrelated ignition and fuel-system problems. OE Match develops replacement components around Porsche applications, using original references and vehicle specifications to assess suitability.

FAQs

Could the wiring produce similar symptoms?
Yes. Loose terminals, corrosion and damaged wiring can interrupt or distort the signal, so inspect these before replacing the sensor.

How should a suspected fault be checked?
Measure the sensor's electrical response using the appropriate workshop procedure and compare the results with the specified values for the vehicle.

Is replacement necessary simply because the sensor is old?
Age alone does not confirm failure. Base replacement on inspection, symptoms and electrical testing.

Check fitment for your specific vehicle (model, year, engine) before ordering.
