Combination Meter System: Inspection: Notes
WARNING: This page is about a different car, the 2003 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When measuring voltage and resistance of the ECM, TCM, or each sensor, use a tapered pin with a diameter of less than 0.64 mm (0.025 in) in order to avoid poor contact. Do not insert the pin more than 2 mm (0.08 in).
