Pinpoint Test F: Intake Air Temperature (IAT) Sensor: Introduction

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.

This pinpoint test is intended to diagnose the following:

harness circuits: IAT, SIGRTN and VPWR
mass airflow/intake air temperature (MAF/IAT) sensor (12B579)
powertrain control module (PCM) (12A650)
