P060E - Internal Control Module Throttle Position Performance
The P060E code indicates that the Engine Control Module (ECM) has detected a performance issue with the throttle position sensor circuit or the internal monitoring of throttle position. This typically means the ECM's internal self-check has found that the throttle position signal is out of expected range or inconsistent, often due to a faulty throttle position sensor, wiring issues, or a failing ECM. The code is set when the ECM detects a malfunction in its ability to accurately read or process throttle position data, which can affect driveability and safety.
1. Most Common Causes
- Internal PCM hardware failure (processor, memory, or ADC)
- Corrupted PCM software or calibration
- PCM power or ground issues (low voltage affecting internal logic)
- Overvoltage or internal short circuit damage to the PCM module
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or limp mode
- Poor acceleration or hesitation
- Rough idle or stalling
3. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for additional codes.
Step 2: Visually inspect the throttle position sensor wiring and connector for damage or corrosion.
Step 3: Test the TPS with a multimeter for proper voltage signal (typically 0.5-4.5V) while opening throttle.
Step 4: Clean the throttle body if carbon buildup is present, then clear codes and test drive.
Step 5: If issue persists, replace the throttle position sensor and recalibrate if necessary.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with P060E as it can cause sudden loss of power or stalling, posing a safety risk. Limp mode may limit speed, but you should have the vehicle diagnosed and repaired promptly.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and sensor replacement, but can be higher if the ECM needs replacement (up to $1000+).
