About the Passport
The Honda Passport is a series of mid-size crossover SUVs that have been manufactured by the Japanese car maker intermittently since 1993. Honda discontinued the model in its second generation in 2002 but brought it back for a third iteration due to the ever-increasing popularity of SUVs in 2019.
The model was originally offered both front-wheel drive and their i-VTM4 all-wheel drive system, but Honda made the latest model exclusive AWD for better performance, particularly offroad.
One of the most common issues that affected the older versions of the Honda Passport is fault code P0300. This code means that the powertrain control module (PCM) has detected random or multiple misfires from the engine.
Because of the random nature of this code, it can be hard to pinpoint what the cause is. Anything that disrupts the optimal air-fuel mixture or the ignition system can be the culprit.
With some luck, this can be caused by a relatively simple issue like faulty or dirty spark plugs or a dirty fuel filter. However, the problem can certainly be far more extensive.
It is always good practice not to ignore misfiring from the engine.
Another issue the Passport has been reported to suffer is with the exhaust gas recirculation (EGR) system. Fault code P0405 being logged means that the EGR valve position sensor has a problem causing low voltage.
While this does not mean that the EGR system is malfunctioning, it does mean that the sensor has a problem, most likely within its circuit.
It is a good idea to look out for electrical issues within its circuit to help find the issue. The problem can also be a faulty EGR valve.
