What Does P060E Mean?
P060E indicates that the ECM/PCM has detected an internal performance fault related to its throttle position (TP) signal processing. The ECM monitors its own internal processing of the electronic throttle body position sensor signals, and this code means the processed values do not meet expected performance criteria. This is a critical electronic throttle control safety code. The driver will likely experience reduced power mode (limp mode), the check engine light, and possibly a throttle warning light.
Safety Warning
Do not drive at normal speeds. This is a safety-critical electronic throttle control fault. The vehicle will likely enter reduced power mode, severely limiting acceleration. If reduced power mode is not active, the throttle could potentially respond unpredictably or stick. Have it towed to a repair facility.
Common Causes
35%
Internal ECM/PCM fault in the throttle position signal processing circuit
25%
Throttle position sensor fault in the electronic throttle body
20%
Wiring fault between the throttle body and ECM — resistance, intermittent connection
12%
Carbon buildup in the throttle body affecting blade movement and sensor readings
8%
ECM 5V reference or ground circuit fault affecting TP sensor accuracy
Diagnostic Steps
1
Monitor both TP sensor signals (TP1 and TP2) on the scan tool while commanding the throttle open and closed using the scan tool's bi-directional control. Both signals should sweep smoothly and proportionally. Any erratic behavior indicates a throttle body or wiring issue.
2
Check the 5V reference and ground at the throttle body connector: reference should be 4.9V-5.1V, ground should be below 0.05V. If reference is low, isolate the circuit by disconnecting other sensors on the same reference.
3
Inspect the throttle body for carbon buildup — remove the air intake duct and visually inspect the throttle blade and bore. Clean with approved throttle body cleaner if carbon is present, then perform a throttle relearn procedure.
4
Measure TP sensor signal voltages at the ECM connector and at the throttle body connector simultaneously. If there is more than 0.1V difference, the wiring has excessive resistance and needs repair.
5
If the throttle body, wiring, and reference circuits all test normal, attempt an ECM reflash. If P060E returns, the ECM's internal TP processing circuit is faulty and the module needs replacement.
