Shift Solenoid A Stuck On

Understand P0752, common causes, and the right TOPDON scanner to diagnose it.

Shift solenoid A mechanically or electrically stuck on.

Common symptoms

  • Wrong gear held
  • Trans slip
  • Check engine light

Typical causes

  • Contaminated solenoid
  • Valve body debris
  • Failed solenoid

What scanner do you need?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Use live data and freeze frame to confirm the fault before replacing parts. ABS, SRS, and network U-codes usually require a full-system scanner.

Diagnostic tips

  • Record freeze frame data when the code first sets
  • Clear the code only after fixing the root cause
  • Check for related pending codes that point to a common issue
  • Verify battery voltage is above 12.4V before chasing sensor codes

Frequently asked questions

Can I diagnose P0752 with a basic code reader?
P0752 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Is it safe to drive with P0752?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
