P0E32 — DC/DC converter voltage sensor A — range/performance fault

P0E32 concerns DC/DC converter voltage sensor A. The monitored response falls outside the expected range or performance relationship. The definition identifies sensor A and a range/performance problem. It does not specify that the measured voltage is simply too high or too low.

Affected system: DC/DC power conversion

Symptoms

• System warning may illuminate
• Affected feature may be unavailable
• Symptoms depend on the vehicle

Possible causes

• Hybrid powertrain sensor, actuator, power supply, connector, or control issue
• Module power, ground, or connector fault
• Vehicle-specific mechanical or control issue

What to check

• Record all available module faults
• Record hybrid and electric powertrain module faults with a compatible scan tool. Check the specified low-voltage supplies and module data first; follow vehicle-specific high-voltage safety procedures for further diagnosis.
• Compare results with vehicle-specific service information
• Verify the repair
• Record hybrid and electric powertrain module faults with a compatible scan tool. Check the specified low-voltage supplies and module data first; follow vehicle-specific high-voltage safety procedures for further diagnosis.
• Repair the verified cause and rescan all affected modules

Also written as: P0E32-00, P0E3200, POE32 (some scan tools add the fault-type byte, e.g. -00).
