How many O2 sensors does a 2013 Ford F150 have?
The 2013 Ford F-150 typically has four O2 sensors.
Across the model year, the pickup generally uses two upstream sensors (before the catalytic converters) and two downstream sensors (after the catalysts). While engine type and exhaust configuration can influence exact placement, four sensors is the standard count for most 2013 F-150s. This article breaks down where they sit and how that setup works, with notes on common variations.
Standard sensor count across the 2013 F-150 engines
These are the typical locations and the standard four-sensor arrangement you’ll find on most 2013 F-150 configurations.
- Upstream O2 sensors: one on each exhaust bank, located before the catalytic converters.
- Downstream O2 sensors: one on each exhaust bank, located after the catalytic converters.
In most configurations, this setup yields a total of four O2 sensors in the exhaust system.
Variations by engine and exhaust configuration
While four sensors is the norm, some engine options or dual-exhaust layouts can alter sensor routing without changing the overall count. Below are the common engine options from the 2013 F-150 lineup and their general sensor arrangements.
- 3.7L V6: typically four O2 sensors (two upstream, two downstream).
- 5.0L V8: typically four O2 sensors (two upstream, two downstream).
- 3.5L EcoBoost V6: typically four O2 sensors (two upstream, two downstream).
If you’re unsure for your specific truck, consult the service manual, inspect the exhaust near the manifolds and catalytic converters, or reference the VIN-specific documentation for your exact build.
Summary
For a 2013 Ford F-150, four O2 sensors is the standard count, with two upstream and two downstream sensors spanning the two exhaust banks. Engine and exhaust configurations can influence placement nuances, but the overall number remains four in most models. This understanding aids diagnostics, maintenance, and the interpretation of sensor readings.
