This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's ignition system. It's like when a light switch is turned on, but the light doesn't come on because there's a break in the wire.
The engine control module (ECM) has detected a problem with the ignition coil circuit for cylinder 'E'. This could mean a wire is broken or disconnected.
The P035A code indicates that the ECM has detected an open circuit or a malfunction in the ignition coil control circuit for cylinder 'E'. This could be due to a wiring issue, a faulty ignition coil, or a problem with the ECM itself.
• Check Engine Light is on
• Engine misfires
• Poor engine performance
• Faulty ignition coil
• Open or shorted ignition coil harness
• Poor electrical connection in the ignition coil circuit
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the ignition coil and wiring for damage.
• Test the ignition coil for proper operation.
• Replace the faulty ignition coil.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive the vehicle.
• OBD-II scanner
• Multimeter
• Socket set
$100 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect ignition system components.
• Ensure all electrical connections are secure.
• Perform routine maintenance as per the vehicle's schedule.
Engine Performance
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Regular maintenance can prevent such issues.
Check with your vehicle manufacturer for warranty coverage on ignition components.
This code has been associated with ignition system issues in various vehicle models over the years.
Moderate – It's important to address this issue to prevent further engine damage.
Driving with a malfunctioning ignition system can lead to increased emissions and potential engine damage.
• Engine running
• Check for misfires during acceleration
The ignition coil is typically located on the engine, near the spark plugs.
Q: Can I drive with a P035A code?
A: It's not recommended to drive for long with this code, as it can lead to engine damage.
Q: How do I reset the Check Engine Light?
A: After repairs, use an OBD-II scanner to clear the code and reset the light.
