Toshiba SHRM Advance R32 aircon P16 error code
Use this Toshiba SHRM Advance R32 P16 error code guide to capture the fault correctly and see what should be checked before parts are quoted.
What does Toshiba P16 mean?
Toshiba SHRM Advance R32 P16 is listed as compressor injection-circuit fault involving PMV5, PMV6, or their coil assignment in SHRM Advance MMY-SUG R32 source row. The loaded row is source-backed by official diagnostic material. Confirm the exact model, series, or signal row before accepting a parts quote.
Low refrigerant, active leak, restriction, or abnormal pressure reading.
Dirty condenser, weak outdoor fan, blocked airflow, or high-load operation.
Pressure sensor, expansion path, or compressor protection after readings are taken.
What to do now
Use these steps before customer action, gas work, a pressure check, or parts quote.
Stop using the unit if P16 returns
Stop using the unit if P16 returns with weak cooling, frost, hissing, or outdoor-unit tripping.
No manufacturer reset steps listed for P16
Capture the complete P16 display and model stickers first. The selected source row lists no customer reset procedure; do not treat a generic power-cycle as manufacturer guidance.

Source-specific guidance
These diagnostic-reference notes help match the code to the exact model. Electrical, refrigerant, wiring, resistance, and component checks are technician work, not DIY steps.
| Source detail | What it says |
|---|---|
| Diagnostic note | Stop repeated reset attempts. A qualified technician should verify the named valves, sensors, airflow, refrigerant circuit, and leak evidence against SVM-22072-1. |
| Singapore / model note | Official Toshiba SVM-22072-1 row for SHRM Advance MMY-SUG R32 heat-pump and heat-recovery systems. The checked manufacturer page is regional rather than a Singapore product listing, so confirm the full model suffix and locally supplied service manual before diagnosis or parts replacement. |
What to check before repair
Use this split to separate safe evidence capture from the tests a technician should prove before quoting parts.
| You can check | Technician should confirm |
|---|---|
| Before taking any system action on P16, take a clear display photo. | Match P16 to low-pressure, high-pressure, leak, or refrigerant-cycle protection. |
| Capture the Toshiba SHRM Advance R32 indoor and outdoor model stickers so the correct family row is used. | Measure operating pressures, coil temperatures, airflow, and outdoor fan condition. |
| The selected source row lists no customer reset procedure. Note whether one room, several rooms, or the whole system is affected. | Leak-check or pressure-test before recommending another refrigerant top-up. |
What changes the next step
These clues decide whether the first check is room-side, shared outdoor-side, refrigerant-side, source-table, or model-family confirmation.
| What you see | What it points to |
|---|---|
| Only one indoor unit shows P16. | The affected room, indoor board path, wiring route, or local component should be checked first. |
| Several rooms or the outdoor unit show the same P16 fault. | Prioritise the shared outdoor side, pressure conditions, airflow, and refrigerant circuit. |
| Cooling is weak, frost appears, or the outdoor unit trips under load. | Pressure, airflow, leak, and condenser checks should come before another top-up. |
| The model family is different from the row you found online. | Use the model or series filter first; same-looking codes can still belong to different diagnostic tables. |
| The model belongs to SHRM Advance MMY-SUG R32 source row. | The loaded row is source-backed by official diagnostic material. Use the matching source row before quoting parts. |
Pressure, leak, or airflow decision
Toshiba SHRM Advance R32 P16 needs measured pressure, airflow, and leak evidence before gas work is approved. Replacement only becomes serious when the leak, compressor, or coil repair is uneconomical.
A top-up alone is poor value if the leak source is not found.
High-pressure faults often come from airflow, condenser, fan, or overcharge conditions.
Coil leaks or compressor-related findings can shift older systems toward replacement.
