Why is my check engine light and VTM-4 light coming on when my car gets wet?
I have a 2009 Honda Pilot EX-L 4WD. I've noticed that when it rains or snows my check engine and VTM-4 light comes on. In about a day or so they both will go away? What could this be???
If this is a problem developing a code would be stored in the computer. I would say go to like Auto Zone to have it checked for codes. If there is a code, then you would know what to look at to fix the problem. You can post the code back here for the meaning and cause.
I have gone by auto part store a had code pulled. Its reading P0175 bank 1 system to rich.
This means...P0175 HONDA - Fuel System Too Rich Bank 2... Possible causes - Faulty front heated oxygen sensor - Ignition misfiring - Faulty fuel injectors - Exhaust gas leaks - Incorrect fuel pressure - Faulty Mass Air Flow (MAF) sensor ......................................................................................................... - Fuel injection system does not operate properly. - The amount of mixture ratio compensation is too large. (The mixture ratio is too rich.)... Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Excessive Fuel Consumption... P0175 Honda Description... With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios. In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the MIL (2 trip detection logic).
Is this just a sensor I can purchase? Oxygen Sensor? I really appreciate your help!
Yes, more than likely the front 02 sensor, the one closest to the engine. The MAF can be cleaned with electrical cleaner at the plugin. Take apart and clean.
Awesome! Sounds easy enough... Thank you for the speedy response.
I've gone online to view this 02 Sensor. They all say " Upstream or Downstream"? Which one would I need to get?
