As an error code, the 7E8 is generally considered low. These emissions may be emitted if an engine malfunction occurs on any vehicle. Other possible problems are a damaged oil pan, upstream exhaust leaks near the vehicle’s O2 sensors, or leaking emissions downstream from a damaged MAF (Mass Air Flow) sensor.
How do I fix my 7EB engine code?
Usually restarting the car is enough to get rid of the code. It can also be turned on just because a sensor sent one signal that was out of range, but not enough to trip an actual check engine light. 7EB is not a problem code.
What does code 7EA engine mean?
7EA is not a trouble code. Some OBD scanners display this code when it needs more info, such as which component group to check. Your engine light may have come on due to a temporary misread of an engine sensor. Clear the Check Engine light, and keep an eye on it. I prefer to use the scanner to reset the CE.
What are the check engine light codes?

How do you read a engine code without a scanner?
Press the odometer’s Trip and Reset buttons while turning the ignition key ON. After turning the key ON, release the odometer Reset and Trip buttons to check if the Diagnostic Trouble Code or DTC appears on the odometer display.
What does a solid check engine light mean?
A solid Check Engine Light can mean something like a loose gas cap, or it can indicate a more in-depth problem like a fuel, timing, or transmission issue. Get your car diagnosed, although the urgency isn’t the same as if the light was flashing at you.
Can a dirty air filter cause a P0101 code?
Can a dirty air filter cause a P0101 code? Oil from an air filter can get onto the MAF sensor element in oil-soaked aftermarket air filters, causing the code P0101 or other MAF-related problems. The code P0101 might be triggered in some Volvo vehicles by a dirty throttle body or vacuum leaks in the PCV system.
