Common Questions
What does P035E mean and how does it affect my car?
P035E indicates a malfunction in the ignition coil circuit 'E', which can lead to misfires, poor fuel economy, and reduced engine performance. If left unresolved, it may cause serious engine problems.
What are the most common causes of P035E and how much does it cost to fix?
The most common causes of P035E include faulty ignition coils, wiring issues, and ECM problems. Repair costs can range from $100 for wiring repairs to over $1,200 for ECM replacement.
Can I drive my car with P035E or should I stop immediately?
It's advisable to limit driving as much as possible if you see the P035E code. Continuing to drive can lead to further engine damage and increased repair costs.
How can I diagnose P035E myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for diagnostic trouble codes, view freeze frame data, and monitor real-time engine parameters to help pinpoint the issue affecting the ignition coil.
What vehicles are most commonly affected by P035E?
P035E often appears in vehicles like the 2015-2018 Ford F-150, Chevrolet Silverado, and GMC Sierra. Check for any manufacturer recalls or technical service bulletins related to this code.
How can I prevent P035E from happening again?
Regular maintenance, including inspecting ignition components and ensuring connections are clean and secure, can help prevent P035E from recurring. Using high-quality parts during repairs also plays a crucial role.
What is P035E?
DTC P035E indicates a malfunction in the ignition coil circuit 'E' of your vehicle, specifically referring to issues with either the primary or secondary circuit of that coil. Ignition coils are vital components in your vehicle’s ignition system, responsible for converting the battery's low voltage into the high voltage necessary to ignite the fuel-air mixture in the engine's cylinders. When this code appears, it signals that the engine control module (ECM) has detected a problem with the electrical signals to or from the ignition coil 'E'. This can lead to misfires, reduced engine performance, and increased emissions. Common symptoms include difficulty starting the engine, rough idling, and decreased fuel efficiency. If left unaddressed, the problem can worsen, potentially leading to further engine damage and costly repairs. Vehicles such as the 2015-2018 Ford F-150, and certain models from Chevrolet and GMC, are particularly susceptible to this code. It's crucial to address this issue promptly to maintain optimal vehicle performance and avoid more extensive repairs down the line.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P035E is present:
- Check engine light illuminates and stays on, indicating a persistent issue that requires immediate attention.
- Engine hesitates during acceleration, leading to a less responsive driving experience and potential safety concerns.
- Fuel economy decreased by 10-15%, resulting in increased fuel expenses and the need for more frequent fill-ups.
- Rough idling occurs, with the engine shaking or vibrating excessively when the vehicle is stationary.
- Difficulty starting the engine, which may require multiple attempts or result in a complete failure to start.
Possible Causes
Most common causes of P035E (ordered by frequency):
- Faulty ignition coil is the most common cause, accounting for about 50% of cases. If the coil is shorted or open, it will stop functioning correctly.
- Wiring issues, such as damaged wires or bad connections, can account for around 30% of the problems. Corrosion or frayed wires can disrupt the signal to the ignition coil.
- ECM issues, though less common, can occur, leading to miscommunication between the engine control module and the ignition coil.
- Less common causes include a blown fuse related to the ignition system, which can disrupt power to the ignition coil.
- Rarely, issues with the crankshaft position sensor can cause problems that lead to a P035E code due to incorrect timing signals.
