The OBD2 code P060E is defined as “Internal Control Module Throttle Position (TP) System Performance,” indicating an issue with the electronic throttle control system. This code is set when the Powertrain Control Module (PCM) detects a malfunction within the throttle position sensor circuit or related components, affecting the vehicle’s drivability and engine performance. Issues can range from intermittent stalling and reduced power mode to complete loss of throttle response.
P060E quick overview
| Meaning | P060E: Internal Control Module Throttle Position System Performance |
| Is it serious? | Yes. This code can lead to unpredictable vehicle behavior, including reduced engine power or stalling, posing safety risks. |
| Possible causes | – Faulty throttle body or accelerator pedal position (APP) sensor – Poor electrical connection or damaged wiring between PCM, APP sensor, and throttle body – PCM issues, including outdated software or hardware failures |
| How to diagnose? | Inspect wiring and connectors for damage, corrosion, or looseness. Perform voltage drop tests on relevant circuits to check for electrical integrity. Check for updated PCM calibration and consider reflashing if necessary. Replace faulty components like the APP sensor or throttle body based on diagnostics. Conduct pin drag tests on connector pins to ensure good contact. |
P060E Meaning
Think of the P060E code as your car telling you there’s a hiccup in how it understands the gas pedal’s instructions. The throttle position system acts like the messenger between your foot on the gas pedal and the engine.
If the message gets jumbled—due to faulty parts like the throttle body or gas pedal sensor, bad wiring, or even a confused car computer (PCM)—your car might not go as expected, or it could enter a “limp” mode to protect itself. Fixing this involves checking the entire message path for damage, ensuring all parts are talking nicely, and updating the car’s computer if it’s speaking an outdated language.

How to fix P060E – learn from mechanics
I looked into P060E service cases at iatn.com website where in the private forums the mechanics seek advice from other mechanics. I looked up a bunch of cases to help you decide how to fix your issue and see what would a real mechanic do to solve it.
Case #1: GMC
Vehicle Information 2007 GMC Envoy SLE 4.2L
Issue + Repair History
- Vehicle sets a P060E code intermittently after varying driving distances.
- Occasional reduced power mode triggered by the code.
- PCM replaced initially but issue persisted.
- Checked all wires between PCM and throttle body, and PCM and APP sensor.
- Freeze frame data showed APP and throttle sensors off by 23%.
- Replaced APP sensor and throttle body without resolving the issue.
Other OBD2 Codes + Test Results
- P060E – Throttle System Malfunction
- Load tested all 14 wires between the APP and PCM, and throttle body and PCM, showing consistent voltage across all circuits.
Mechanic Suggestions
- Suggested rechecking wiring from APP to PCM and TP sensors from throttle body to PCM for possible chafing or rubbing.
- Recommended ensuring PCM has the updated calibration and verifying good power and grounds at ECM, APP, and TPS.
- Proposed performing a pin drag test on all related circuits and considering a reflash for the throttle-by-wire system.
- Advised against cutting wires unless absolutely necessary due to the vehicle’s relatively new age.
Final Fix
- Rewired all circuits from PCM to APP and PCM to throttle body, addressing potential internal wire breaks that weren’t detected by voltage drop testing, ultimately resolving the issue.
Case #2: Chevrolet
Vehicle Information 2005 Chevrolet Colorado Z85 LS 3.5L
Issue + Repair History
- Initially experienced “power engine reduced, traction fault” message and CEL with code P060E.
- Replaced PCM, but problem persisted with the addition of code P2135.
- Replaced throttle body and accelerator pedal position sensor to no avail.
- Checked connectors and wiring for visible damage but found none.
Other OBD2 Codes + Test Results
- P060E – Throttle System Malfunction
- P2135 – Accelerator Pedal Position Sensor
- No specific test results mentioned.
Mechanic Suggestions
- Recommended performing voltage drop tests on battery cables and checking battery terminal for corrosion.
- Suggested checking wiring by the MAP sensor and air injection solenoid for damage.
- Advised checking fail records for VREF PIDs and ensuring VREF is not pulled low during issues.
- Some suggested running all new wiring from throttle body to PCM and PCM to APP.
Final Fix
- Rewired throttle body to PCM harness, discovered a faulty gray wire in the 5-volt feed from PCM, replaced the wire and terminal, and soldered a new harness to resolve the issue.
Case #3: Dodge
Vehicle Information 2010 Dodge Avenger R/T 2.4L
Issue + Repair History
- Vehicle towed in with P060E ECT Level 2 TPS Performance code.
- Throttle plate did not move during throttle plate test.
- Calibrated pedal to throttle body, performed throttle plate test again, and restarted.
- Check engine light remained on with codes P0123 TPS/APP Circuit High and P0222 TPS 2 Circuit Low.
- Relearn test performed twice, codes disappeared.
- Customer reported “lightning bolt of death” on dash during crawl-speed incident.
Other OBD2 Codes + Test Results
- P060E – ECT Level 2 TPS Performance
- P0123 – TPS/APP Circuit High
- P0222 – TPS 2 Circuit Low
- No specific test results mentioned.
Mechanic Suggestions
- Suggested labscope testing of wires at ETC, PCM, and APP for loss of reference voltage or ground.
- Advised checking large green 43-pin connector in driver’s side kick panel area for water damage or loose terminals.
- Recommended saving freeze frame data when codes occur to analyze TPS and APP voltages.
- Suggested swapping MAP sensor if equipped, as it resolved similar symptoms in another Chrysler vehicle.
Final Fix
- Found a meth pipe stuck in air snorkel during second inspection, removed meth pipe and throttle plate, issue resolved.
How to diagnose P060E
I made you an overview of solving this DTC, based on all the advice that was suggested by certified mechanics to address this issue in previously mentioned service cases.
| Diagnostic Step | Explanation |
|---|---|
| Inspect wiring and connectors | Look for any signs of damage, corrosion, or loose connections that could interrupt signals. |
| Voltage drop tests on circuits | Ensure electrical connections are solid and without resistance that could hinder performance. |
| Check PCM for updates | Outdated software can cause miscommunication; updating may resolve issues. |
| Replace APP sensor/throttle body | Faulty parts can disrupt communication between the pedal and engine. |
| Pin drag tests on connectors | Ensures that all connectors are making proper contact and haven’t loosened over time. |
| Reflash the throttle-by-wire system | Updates the electronic control strategies, possibly correcting the malfunction. |
| Rewire critical circuits if necessary | Sometimes, undetectable issues within the wiring require a fresh start with new wires. |
