This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a higher voltage than expected from certain sensors. It's like if your remote control was getting too much power from its batteries.
The vehicle's control module is detecting a voltage level from one or more sensors that is higher than the specified range.
P1897 indicates that the supply voltage to one or more of the vehicle's sensors is higher than the expected range. This could be due to a fault in the voltage supply circuit, a malfunctioning sensor, or an issue with the vehicle's power management system.
• Check Engine Light on
• Erratic engine performance
• Poor fuel economy
• Faulty voltage regulator
• Damaged wiring or connectors
• Defective sensor
Voltage Regulator: A device that maintains a constant voltage level.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Use a multimeter to check the voltage at the sensor connectors.
• Inspect wiring and connectors for damage or corrosion.
• Test the voltage regulator for proper operation.
• Replace faulty voltage regulator.
• Repair or replace damaged wiring or connectors.
• Replace defective sensor.
• Multimeter
• OBD-II scanner
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect electrical connections.
• Ensure battery terminals are clean.
• Check for recalls related to electrical systems.
Sensor Issue
• Avoid driving the vehicle until the issue is resolved.
• Consult a professional mechanic for a thorough diagnosis.
Check with the vehicle manufacturer for warranty coverage on electrical components.
P1897 has been associated with issues in vehicles with aging electrical systems or after aftermarket modifications.
Moderate – It is advisable to address this issue soon to avoid potential damage to the vehicle's electrical system.
Driving with unresolved electrical issues can lead to further damage and may not comply with emissions regulations.
• Engine running
• All electrical accessories off
The sensors are typically located on or around the engine and transmission.
Q: Can I drive with a P1897 code?
A: It's not recommended to drive with this code active, as it can lead to further electrical issues.
Q: Will a P1897 code clear itself?
A: The code may clear if the issue is resolved, but it's best to use an OBD-II scanner to confirm.
