Speedometer Test
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.
