This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble keeping track of time when the engine is turned off.
The ECM (Engine Control Module) or PCM (Powertrain Control Module) has a built-in timer to monitor the duration the engine is off. This code indicates a problem with this timer's performance.
The P2610 code is set when the ECM/PCM detects a malfunction in the internal engine off timer, which is responsible for tracking the time the engine remains off. This timer is crucial for various diagnostics and operations, including emissions control and readiness checks.
• Check Engine Light illuminated
• Potentially reduced fuel efficiency
• Possible issues with vehicle readiness monitors
• Faulty ECM/PCM
• Software issue in the ECM/PCM
• Battery voltage issues
• Corroded or damaged ECM/PCM connectors
ECM: Engine Control Module
PCM: Powertrain Control Module
• Check for other related codes and address them first.
• Inspect ECM/PCM connectors for damage or corrosion.
• Test the battery and charging system for proper voltage.
• Reprogram or update ECM/PCM software if necessary.
• Clean or replace ECM/PCM connectors if corroded.
• Replace or reprogram the ECM/PCM if faulty.
• Ensure battery and charging system are functioning correctly.
• OBD-II scanner
• Multimeter
• Battery tester

• Toyota Camry
• Ford F-150
• Honda Accord
• Regularly check battery health and connections.
• Keep ECM/PCM software updated.
• Ensure proper vehicle maintenance.
Engine Performance
• If the check engine light is on, have the vehicle inspected promptly.
• Avoid disconnecting the battery unnecessarily.
Check with the vehicle manufacturer for warranty coverage on ECM/PCM issues.
This code has been more prevalent in vehicles with aging ECM/PCMs or those with frequent battery disconnections.
Moderate – It should be addressed to ensure proper vehicle operation and emissions compliance.
Ignoring this code may lead to increased emissions and potential vehicle inspection failures.
• Engine off for a prolonged period
• Battery voltage stable
The ECM/PCM is typically located in the engine bay or passenger compartment, depending on the vehicle model.
Q: Can I drive with a P2610 code?
A: Yes, but it's best to have it checked soon to avoid potential emissions issues.
Q: Will a P2610 code cause my car to fail an emissions test?
A: It might, as it can affect the readiness monitors required for emissions testing.
