P1686 Engine Trouble Code
Meaning of P1686 engine trouble code is a kind of powertrain trouble code and theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $240-$400 depending on the car, but that's usually the cost of parts because the labor is relatively simple.
P1686 Fault Symptoms :
If one of these reasons for P1686 code is occuring now you should check P1686 repair processes.
Now don't ask yourself; What should you do with P1686 code ?
The solution is here :
P1686 Possible Solution:
Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.
P1686 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Fuel And Air Metering||Fuel Temperature Sensor B Circuit Range/Performance||Ignition/Distributor Engine Speed Input Circuit Malfunction||Ignition Coil A Primary/Secondary Circuit Malfunction|
The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.
P1686 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP1686 engine trouble code is about Ignition Coil A Primary/Secondary Circuit Malfunction.
Main reason For P1686 CodeThe reason of P1686 OBD-II Engine Trouble Code is Fuel Temperature Sensor B Circuit Range/Performance.
P1686 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set.
