Speedometer Test
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2001 Toyota Prius, 2001 Toyota MR2, 2001 Toyota ECHO, 2001 Toyota Corolla, and 2001 Toyota Celica. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
On Avalon, Celica and MR2, speedometer resistance can be measured at back of instrument cluster.
- Using DVOM, measure resistance between terminals "A" and "B", and between "C" and "D" while indicator is resting on stopper pin. See Figure, Figure and Figure . Resistance should be 250 ohms between each set of terminals. If resistance is not as specified, replace speedometer.
- Ensure tires are correct size and inflated properly. Place vehicle on standard speedometer tester. Compare tester with speedometer readings. See SPEEDOMETER TEST table. If vehicle speedometer readings are not within allowable range, replace speedometer. If speedometer does not operate at all, check vehicle speed sensor. See appropriate SYSTEM & COMPONENT TESTING article in ENGINE PERFORMANCE.
