Common Questions
What does P071E mean and how does it affect my car?
The P071E code indicates a problem with the transmission fluid temperature sensor. If this sensor is malfunctioning, your vehicle may experience poor shifting, overheating, or even transmission failure if not addressed. It's crucial to diagnose and repair the issue promptly to maintain optimal vehicle performance.
What are the most common causes of P071E and how much does it cost to fix?
Common causes of P071E include a faulty transmission fluid temperature sensor, damaged wiring, or low fluid levels. Repair costs can range from $150 for sensor replacement to $800 for ECM replacement, depending on the severity of the issue.
Can I drive my car with P071E or should I stop immediately?
Driving with a P071E code is not recommended as it can lead to serious transmission issues. It's best to address the problem as soon as possible to avoid further damage and costly repairs.
How can I diagnose P071E myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for DTCs and retrieve freeze frame data. This data gives you insight into what was happening when the code was triggered, helping you diagnose whether the issue lies with the sensor, wiring, or other components.
What vehicles are most commonly affected by P071E?
P071E is commonly found in vehicles like the 2013-2017 Ford Escape, 2014 Chevrolet Malibu, and 2015 Honda Accord. Owners of these models should be particularly vigilant about transmission performance and sensor health.
How can I prevent P071E from happening again?
To prevent P071E from recurring, regularly check and maintain your transmission fluid levels, ensure connections to the temperature sensor are secure, and schedule routine diagnostics to catch any potential issues early.
What is P071E?
The DTC code P071E refers to a Transmission Fluid Temperature Sensor Range/Performance Problem. This code is triggered when the Engine Control Module (ECM) detects that the temperature readings from the transmission fluid temperature sensor are out of the expected range. It's crucial for the transmission to operate efficiently that the fluid temperature is monitored accurately. If the ECM perceives that the sensor is providing readings that are higher or lower than expected, it will trigger the check engine light and store this code. This could lead to issues such as poor shifting, overheating of the transmission, or even complete transmission failure if not addressed promptly. For many vehicle owners, especially those driving models like the 2013-2017 Ford Escape, Chevrolet Malibu, and Honda Accord, understanding this code is vital to maintaining optimal vehicle performance and ensuring a longer lifespan for the transmission system. Ignoring P071E can result in serious damage to the transmission, leading to costly repairs that could have been avoided with timely diagnosis and action.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P071E is present:
- The check engine light stays on constantly, indicating a persistent issue with the transmission system.
- Engine hesitates during acceleration, which can manifest as a lag or delay when trying to speed up.
- Fuel economy decreased by 10-15%, resulting in more frequent trips to the gas station.
- Unusual noises coming from the transmission, such as grinding or whining, especially during gear shifts.
- Slipping gears or difficulty in shifting between gears, which may cause erratic driving behavior.
Possible Causes
Most common causes of P071E (ordered by frequency):
- The most common cause of P071E is a faulty transmission fluid temperature sensor, with about 60% likelihood. This could be due to wear and tear or electrical issues.
- A second cause could be damaged wiring or connectors leading to the sensor, which can disrupt the communication between the sensor and the ECM.
- Another potential cause is low transmission fluid levels or contaminated fluid, which can skew temperature readings. Regularly checking fluid levels can prevent this.
- Less commonly, a malfunctioning ECM could misinterpret data from the sensor, although this is rare and usually follows a series of other sensor failures.
- In rare cases, issues with the transmission control module (TCM) can also lead to the P071E code being triggered, necessitating a deeper diagnostic.
