P011E Lincoln Code - Engine Coolant Temperature 1 / Ambient Air Temperature Correlation
Quick Answer
The Engine Coolant Temperature (ECT) Sensor is a thermistor device in which resistance changes with temperature. Common causes include Biased Engine Coolant Temperature (ECT) or Ambient Air Temperature (AAT) Sensor, Faulty Engine Coolant Temperature Sensor, Faulty Intake Air Temperature (IAT Sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P011E Lincoln Description
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so varying the resistance of the passive sensor causes a variation in total current flow. The voltage that is dropped across a fixed resistor (pull-up resister) in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The ECT Sensor is located in an engine coolant passage and measures the engine coolant temperature. The PCM uses the engine coolant temperature input for fuel control and for cooling fan control. The ECT Sensor can be a threaded or twist lock type.
This Diagnostic Trouble Code (DTC) is set when the ECT and Ambient Air Temperature (AAT) sensor readings differ by greater than a calibrated value.
What are the Possible Causes of the DTC P011E Lincoln?
- Biased Engine Coolant Temperature (ECT) or Ambient Air Temperature (AAT) Sensor
- Faulty Engine Coolant Temperature Sensor
- Faulty Intake Air Temperature (IAT Sensor
How to Fix the DTC P011E Lincoln?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P011E Lincoln code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P011E Lincoln Code
What does the OBDII code P011E mean in a Lincoln vehicle?
Code P011E indicates a correlation issue between the engine coolant temperature (ECT) sensor and the ambient air temperature (AAT) sensor readings.
What are the common symptoms of code P011E in Lincoln vehicles?
Symptoms may include the check engine light turning on, poor fuel efficiency, irregular engine performance, or difficulties in cold-weather starts.
What causes the P011E code to appear in Lincoln vehicles?
Common causes include a faulty ECT sensor, AAT sensor, wiring issues, or a malfunctioning PCM (powertrain control module).
Can a dirty or corroded sensor trigger the P011E code?
Yes, dirt, corrosion, or physical damage to the ECT or AAT sensors can cause inaccurate readings, leading to the P011E code.
How do you diagnose the P011E code in Lincoln vehicles?
Diagnosis involves scanning the vehicle for codes, inspecting the ECT and AAT sensors, checking wiring connections for damage, and comparing temperature readings through live data.
Is it safe to drive a Lincoln with the P011E code active?
While the vehicle may still operate, prolonged driving with the P011E code can lead to engine performance issues or damage, so it is best to address it promptly.
How is the P011E code typically fixed in Lincoln vehicles?
Repairs may include replacing a faulty ECT or AAT sensor, repairing damaged wiring, or reprogramming or replacing the PCM if necessary.
Can extreme weather conditions cause the P011E code?
Yes, extreme heat or cold can sometimes affect sensor readings, especially if the sensors are aging or compromised.
Will clearing the P011E code solve the issue permanently?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be addressed to prevent the code from returning.
How much does it cost to repair the P011E code in Lincoln vehicles?
Repair costs vary but typically range from $50 to $300, depending on whether the issue is a sensor replacement, wiring repair, or PCM reprogramming.
