Description

Bosch 17158 left oxygen sensor for the 2003-2006 Porsche Cayenne V8 4.5L measures the air-fuel ratio in the exhaust and reports it to the ECU. This Bosch O2 sensor is a wide-band unit that gives the ECU more detail than a switching sensor.

Continuous, high-precision readings across the full lambda range
Reaches operating temperature in under 7 seconds for quick closed-loop control
Built to withstand exhaust up to 1,880°F, with an integrated heater element and a TSP coating that resists vibration, corrosion and contamination
Ceramic construction and optimized heater control for steady performance through rapid load changes and heat cycles

Quick facts

Fits: 2003-2006 Porsche Cayenne V8 4.5L
Position: Upstream left
Material: Metal housing
Condition: New

A lit check engine light, poorer fuel economy or a rough idle can mean a worn oxygen sensor, but other faults cause them too. Before you replace this sensor, rule out damaged wiring or a connector, an exhaust leak near the sensor and other stored fault codes. If this sensor is the cause, this one replaces it.

Frequently Asked Questions

Is the Bosch 17158 the right Porsche Cayenne oxygen sensor for 2003-2006 models with the V8 4.5L?

Yes. The Bosch 17158 left upstream oxygen sensor fits the 2003-2006 Porsche Cayenne V8 4.5L, and this listing covers that left upstream position.

Does this wide-band oxygen sensor come with a wiring harness and anti-seize?

Yes. The sensor comes with its wiring harness, and conductive anti-seize is already applied to the threads. The right side is a separate part.

What thread and hex size does the Bosch 17158 use?

This left oxygen sensor has an M18 - 1.5 thread and a 22 mm hex. It has 6 terminals and a threaded mount.

Is this Bosch premium oxygen sensor a wide-band or narrow-band type?

It is a wide-band sensor. It gives the ECU continuous air-fuel ratio readings across the full lambda range rather than the switching signal of a traditional sensor.

How quickly does the Bosch 17158 reach operating temperature?

The Bosch 17158 reaches operating temperature in under 7 seconds, so the ECU gets a usable signal quickly for closed-loop control.
