⚙️ P060D Code – Internal Control Module Accelerator Pedal Position Performance

The P060D trouble code indicates that the Engine Control Module (ECM) detected an internal processor error while monitoring the Accelerator Pedal Position (APP) sensor. In simple terms, the ECM is not interpreting throttle input data correctly. This is an internal performance fault — not a wiring short — and often related to low voltage, corrupt ECM memory, or sensor feedback mismatch.

Drivers commonly experience symptoms similar to P060A Internal Processor Performance or P0604 RAM Error. The iCarsoft CR PRO S (view product) can read, reset, and live-monitor throttle position data to diagnose this issue precisely.

🔍 What Does P060D Mean?

The ECM continuously compares input signals from the accelerator pedal sensors (APP1 and APP2). When their voltage signals fall outside of expected correlation, or when the processor cannot interpret their data within a normal time frame, it logs P060D Internal Control Module Accelerator Pedal Position Performance. This is especially common after throttle body replacement or when battery voltage fluctuates during ignition.

⚠️ Common Symptoms of P060D

• Reduced engine power or limp mode
• Unresponsive accelerator pedal
• Delayed throttle response on cold start
• Check Engine Light illuminated
• Related codes like P2122, P2138, or P060A

🧾 Common Causes

• ECM internal processor fault or memory corruption
• Low system voltage during startup
• Throttle body contamination or stuck plate
• Accelerator Pedal Position (APP) sensor fault
• Loose ECM connectors or poor grounding

🧰 How to Diagnose P060D Using iCarsoft CR PRO S

The iCarsoft CR PRO S supports in-depth ECM testing, throttle calibration, and live sensor correlation monitoring. Follow these steps:

1. Connect the CR PRO S to the vehicle’s OBD-II port and switch ignition ON.
2. Select “ECM → Read DTCs” to confirm P060D and any related accelerator or voltage codes.
3. Enter “Live Data” and graph APP Sensor 1 and APP Sensor 2 voltages — both should rise smoothly as you depress the pedal.
4. If voltages are erratic, inspect pedal harness or connector pins for corrosion.
5. Use “Special Functions → Throttle/APP Reset” to recalibrate sensor range after cleaning or replacement.

If both sensors behave correctly yet the P060D returns, it points to internal ECM performance degradation — often similar to P060A conditions.

🔧 Recommended Fixes for P060D

• Clean the throttle body using approved cleaner
• Perform accelerator pedal calibration with a scan tool
• Check voltage (should be 13.8–14.4V while running)
• Repair damaged wiring or connectors at pedal/ECM
• Update ECM firmware; replace ECM if fault persists

💡 Real Workshop Example

A 2017 Mercedes C-Class displayed P060D with symptoms of “Reduced Power Mode.” Using the iCarsoft CR PRO S, the technician confirmed APP sensor voltage fluctuated below 0.45V intermittently. After cleaning the pedal connector and performing an Accelerator Pedal Learning Procedure, the issue was resolved without ECM replacement. This shows that not all internal processor codes require expensive repairs.

🧠 Pro Tips

• Never perform ECM software updates with a weak battery — it risks memory corruption and processor errors.
• If the vehicle had a recent throttle body replacement, always perform a full adaptation reset.
• Use the CR PRO S “Voltage Graph” to catch intermittent drops below 11.5V that can trigger P060D.
• Inspect engine grounds and ECM casing for moisture before assuming hardware failure.

❓ FAQ – Understanding P060D

• Can I drive with code P060D?
  It’s not recommended — limp mode may limit throttle response, especially in traffic.
• Does replacing the pedal fix it?
  Sometimes. If both APP sensors report clean voltages but the code remains, ECM software or voltage supply is the issue.
• Is P060D the same as P2138?
  Not exactly. P2138 refers to sensor correlation between APP1/APP2, while P060D points to internal ECM logic fault interpreting them.
• What scan tool can reset throttle adaptations?
  The iCarsoft CR PRO S performs both Throttle Body and Accelerator Pedal Learning procedures across most major brands.

📘 Final Thoughts

The P060D Internal Control Module Accelerator Pedal Position Performance code often results from unstable voltage or pedal sensor noise confusing the ECM. Before replacing major components, use the iCarsoft CR PRO S to perform live pedal voltage monitoring, throttle adaptation, and full ECM health checks. Proper calibration and power stability usually clear the code permanently.
