EGR Positioner Output Stage Over Temperature
This means a part of the car that helps control pollution is getting too hot.
The EGR (Exhaust Gas Recirculation) system helps reduce emissions by recirculating a portion of the exhaust gases back into the engine. This code indicates that the EGR positioner, which controls the valve, is overheating.
The EGR positioner is responsible for accurately controlling the position of the EGR valve. If it overheats, it may not function properly, leading to increased emissions and potential engine performance issues. This code is triggered when the temperature of the output stage of the EGR positioner exceeds a predefined limit.
• Check for any stored trouble codes
• Inspect the EGR positioner for damage or overheating
• Test the EGR circuit for electrical shorts
• Replace the EGR positioner if faulty
• Repair any electrical shorts in the EGR circuit
• Ensure proper engine cooling system function
• OBD-II scanner
• Multimeter
• Thermal camera or infrared thermometer

Engine Performance
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional
• Avoid driving under heavy load until repaired
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has been associated with vehicles that have higher mileage or those with poor maintenance records.
Moderate – Address soon to prevent further engine damage.
Ignoring emissions-related issues can lead to failing emissions tests and increased environmental pollution.
• Engine at operating temperature
• Vehicle in idle or under light load
The EGR positioner is typically located near the engine, connected to the EGR valve.
Q: Can I drive with a P1269 code?
A: It's not recommended to drive for extended periods with this code as it can lead to increased emissions and potential engine damage.
Q: How do I know if my EGR positioner is faulty?
A: Symptoms include poor engine performance, increased emissions, and a Check Engine Light. A diagnostic scan can confirm the issue.
