A flashing check engine light is your Honda Odyssey’s way of saying “I have a serious problem, don’t ignore me”.
Here are the common Honda Odyssey Check Engine Light Flashing
- Loose gas cap
- Oxygen sensor
- Catalytic Converter
- Spark Plugs
- Transmission Problems
- Fuel Pump
These are the fault, errors arises when check engine light flashing.
How to diagnose these fault?
To diagnose these faults, a scanner or Obd2 device need to run on a vehicle, it pop up with the faults as code errors as start with P.
How to repair these Code Errors?
Common Fault Codes
P0456 (Evaporative Emissions System – Small leak detected)
The apparent loose fuel tank cap, this code can be caused by cracks in EVAP hoses or vapor canister. Purge valves or canister vent valve can be faulty, also.
P0420 (Catalyst System Efficiency Below Threshold)
This code in your Honda, it means that readings from your downstream O2 sensor show that amount of oxygen in the exhaust is incorrect. This can be caused by a faulty catalytic converter.
Exhaust leaks or incorrect ignition timing can cause this code. It is wise to rule out all these possibilities before changing the catalytic converter, as they are very expensive.
P0141 (Heated oxygen sensor 2, bank 1 heater control circuit malfunction)
Downstream O2 sensor in your Honda have an integrated heating element to help it reach operating temperatures as soon as possible.
P0740 (Transmission Lock-Up Control System Fault)
This can be caused by something simple as low transmission fluid level or dirty transmission fluid. Other common transmission problems.
P0401 (Exhaust Gas Recirculation Insufficient Flow)
Insufficient flow through this system can be caused by blocked or cracked EGR tube or a faulty EGR valve.
Another possibility is a vacuum related issue, as the EGR valve is vacuum operated.
P1457 ( Evaporative Emissions Control System Leakage EVAP Canister System)
Similar problem as it happened with P0401.
Honda P0137 (Oxygen Sensor Circuit Low Voltage B1S2)
It is best to test the O2 sensor resistance to confirm the oxygen sensor is the culprit.
Other possible causes that can trigger P0137 include damaged wire harness to the O2 sensor, engine misfire, and fuel pressure too low.
