P062C

Symptoms

• The Check Engine light comes on
• Incorrect speedometer readings
• Unstable automatic transmission operation
• Cruise control failure or malfunctions
• Errors in ESP/ABS systems using VSS data

Causes

• Internal VSS signal processing error in ECU
• Noisy or unstable speed sensor input signal
• Inconsistency of VSS data from different sources (transmission sensor vs. ABS)
• ECU firmware software failure
• Physical ECU malfunction

How to Fix

1. Read error codes from all units - ECU, ABS, transmission
2. Check real speed readings through the scanner while driving
3. Check Transmission Speed Sensor (VSS) - Resistance and Signal
4. Check wiring from VSS to ECU
5. If there is a discrepancy between data from different sources, find the reason for the discrepancy
6. If external sources are working - ECU diagnostics
