P060EInternal Control Module Throttle Position Performance

Q: What does code P060E mean?

Internal Control Module Throttle Position Performance. P060E is a generic powertrain code indicating that the engine control module (ECM) has detected an internal performance fault in its own throttle position monitoring circuitry. The ECM compares the throttle position signal from its internal sensors against expected values and other correlated inputs, and when the discrepancy exceeds a calibrated threshold, it stores this code and typically illuminates the check engine light.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Reduced engine power or limp mode, where the vehicle may be limited to a low speed
Hesitation or stumble during acceleration
Unstable or fluctuating idle speed
Poor throttle response or a delay when pressing the accelerator pedal
In rare cases, the engine may stall or fail to start

Common causes, most likely first

Faulty or failing engine control module (ECM) internal circuitry
Corroded, loose, or damaged wiring or connectors at the throttle body or ECM
Voltage supply or ground issues to the ECM or throttle body
A malfunctioning throttle position sensor (TPS) or throttle body assembly sending erratic signals
Software corruption or outdated calibration in the ECM
Electrical interference from aftermarket accessories or poor grounding

How to diagnose and fix it

Perform a thorough visual inspection of the throttle body, TPS, and ECM connectors for corrosion, loose pins, or damage
Check battery voltage and ensure the charging system is functioning properly, as low voltage can cause false codes
Use a scan tool to view live throttle position data and compare it to the accelerator pedal position to verify consistency
Inspect the wiring harness between the throttle body and ECM for chafing, shorts, or open circuits
Check for technical service bulletins (TSBs) or software updates for the ECM that address throttle position performance
If all external components and wiring test good, follow the manufacturer's diagnostic flow for internal ECM fault confirmation
Replace and reprogram the ECM only after confirming the internal fault with the manufacturer's specific tests

Before you replace the ECM

A weak or failing battery or poor ground connection can cause the ECM to set P060E even when the module itself is healthy, so always load-test the battery and check grounds first.
Aftermarket electronic throttle controllers or piggyback tuners can interfere with the throttle position signal and trigger this code, so remove any such devices before diagnosing.
The code can be set by a momentary glitch in the throttle position signal that does not recur, so clearing the code and test-driving may be appropriate if no other symptoms are present.
A dirty throttle body can cause the blade to stick slightly, leading to a mismatch between commanded and actual throttle position that the ECM interprets as an internal performance fault.
Some vehicles require a throttle body relearn or idle air volume relearn procedure after cleaning or replacement, and skipping this step can cause the code to return.

Can I keep driving with P060E?

If the vehicle is in limp mode or has severely reduced power, avoid driving until diagnosed to prevent unsafe situations. If the only symptom is the check engine light and the car drives normally, you can drive cautiously to a repair shop, but avoid aggressive acceleration or heavy loads.
