Common Questions
What does P068A mean and how does it affect my car?
P068A indicates that there's a problem with the power relay circuit for your engine's control module. This can lead to poor engine performance, stalling, or reduced fuel efficiency if not addressed. Over time, ignoring this code can result in more serious engine issues.
What are the most common causes of P068A and how much does it cost to fix?
The most common causes include a faulty power relay, damaged wiring, or a weak battery. Repair costs can range from $100 for a relay replacement to upwards of $1,500 if the ECM needs to be replaced.
Can I drive my car with P068A or should I stop immediately?
It's best to stop driving your vehicle if you see the P068A code. Continuing to drive can worsen the issue and lead to more severe engine problems, which could be costly to repair.
How can I diagnose P068A myself using GeekOBD APP?
You can use the GeekOBD APP to scan your vehicle for diagnostic trouble codes. Once you pull the P068A code, you can review the freeze frame data to see what conditions were present when the code was triggered, helping you pinpoint the issue.
What vehicles are most commonly affected by P068A?
Common vehicles affected by P068A include various Ford models (2010-2018), Chrysler vehicles from the same years, and certain GM models. It's important to check for any recalls or technical service bulletins related to this code.
How can I prevent P068A from happening again?
Regular maintenance, including checking the power relay, battery health, and wiring condition, can help prevent P068A. Keeping your vehicle’s electrical system in good shape is key.
What is P068A?
The diagnostic trouble code P068A is indicative of a power relay control circuit issue associated with the Engine Control Module (ECM). This code often signifies that the ECM is not receiving the correct voltage, which can lead to various performance problems in your vehicle. The ECM is a critical component that manages the engine's performance, including fuel injection, ignition timing, and emissions control. When there's a malfunction or irregularity in the power relay circuit, it can affect the ECM's ability to communicate with other systems in the vehicle, leading to symptoms such as poor fuel economy, engine misfires, or even stalling. In practical terms, if you see this code, it means your vehicle's engine management system is not functioning optimally, and you should address the issue promptly to avoid worsening problems. Commonly affected vehicles include models from Ford, Chrysler, and General Motors manufactured between 2010 and 2018, which have been reported to experience related issues due to worn out wiring or faulty relays. If you're experiencing symptoms associated with this code, it's advisable to consult a professional mechanic for an accurate diagnosis and timely repairs.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P068A is present:
- Check engine light stays on constantly, indicating that the vehicle's onboard computer has detected a problem.
- Engine hesitates during acceleration, which may feel like a delay or stuttering when you press the gas pedal.
- Fuel economy decreased by 10-15%, meaning you might be filling up more often without any apparent reason.
- Engine may stall unexpectedly, especially when idling or under load, which can be dangerous.
- Poor engine performance overall, leading to reduced power output and responsiveness.
Possible Causes
Most common causes of P068A (ordered by frequency):
- The most common cause of P068A is a faulty power relay, which has a likelihood of around 50%. This can happen due to wear and tear over time.
- Another potential cause is damaged wiring or connectors in the ECM circuit, which can lead to intermittent connectivity issues.
- A third cause could be a weak battery or poor ground connections that prevent the ECM from receiving the proper voltage. Regular checks on battery health can prevent this.
- Less common but serious causes include a defective ECM, which would require replacement and could be costly.
- A rare cause might be a malfunctioning ignition switch, which can affect the power supply to various components, including the ECM.
