Bosch Oxygen Sensor P/N:17102
Bosch 13338 oxygen sensor for the 2001-2003 Toyota Highlander V6 3.0L and other vehicles measures air-fuel ratio in the exhaust and reports it to the ECU. This heated narrow-band sensor is made for the downstream position.
A worn oxygen sensor can show up as a lit check engine light, higher fuel use or a failed emissions test. Other faults can produce those readings too, so with the engine off and cool, first look over the sensor's wiring and connector for cracks or burn marks. A shop can test the signal itself.
This listing is one downstream oxygen sensor for the 2001-2003 Toyota Highlander V6 3.0L and the 1999-2003 Lexus RX300 V6 3.0L. Each of them takes one.
Fit and size
Build and materials
One oxygen sensor with its wiring harness. A mounting bracket is not included, and the old one may not be reusable.
Is this the right O2 sensor for a 2003 Toyota Highlander V6 3.0L?
Yes. Bosch 13338 fits the 2001-2003 Toyota Highlander V6 3.0L, which includes 2003, and each vehicle takes one sensor.
Does this Bosch premium oxygen sensor include the wiring harness?
Yes, the wiring harness comes with the sensor. A mounting bracket is not included.
What thread size does this Bosch O2 sensor have?
Bosch 13338 has an M18 - 1.5 thread and a 22 mm hex. Length from the sealing surface to the end of the connector is 18.5 in.
Can a worn downstream oxygen sensor cause a rough idle?
It can, along with a lit check engine light or worse fuel economy, but other parts can cause these too. A shop can read the sensor's signal with a scan tool.
How fast does this oxygen sensor reach operating temperature?
In under 10 seconds, which makes the signal available to the ECU quickly for closed-loop control and cold-start performance.
