In rare cases, the MAF sensor can also be damaged by oil vapors flowing back out of the crankcase ventilation after the engine has been switched off. When driving fast in heavy rain, water can occasionally pass through the air filter, which can severely impair the function of the MAF sensor. However, the sensor can also malfunction earlier. With a noticeable loss of performance and high mileage, a defective MAF sensor should definitely be considered. As the mileage increases on your Trax, it can happen that increasingly inaccurate values are sent to the engine control unit. The mass air flow sensor is a wearing part. This can cause the engine warning light to illuminate in the instrument cluster and the fault can be read out by a diagnostic device. The engine runs too “lean” or too “rich”. The optimal amount of fuel can no longer be calculated which results in either too little or too much fuel injected into the combustion chambers. If the MAF sensor is defective or dirty, it does not send correct measured values to the control unit of Trax. What happens when MAF sensor malfunctions in Chevy Trax? It is not only important for power delivery in your Trax, but also for the lowest possible pollutant emissions. The mass air flow sensor is part of the engine’s intake system and is located between the air filter box and the throttle valve. Dirty or faulty mass air flow sensor (MAF)ĭefective or dirty mass air flow sensor (MAF) in your Chevy Trax can result in loss of power, uneven engine running, erratic idling, misfires, poor exhaust emission values including black smoke. So this is the first thing you should check. Replacing the filter on your Trax takes a few minutes and does not require any special knowledge. In the worst case, the engine can stall if the air filter is extremely clogged. This ultimately also increases fuel consumption. It’s just impossible.If the air filter is dirty in your Chevy Trax, it can have a negative effect on the performance of the engine, as less air passes through the dirty filter which suffocates the engine. But this moment in time, this group of people, it won’t happen again. I hope to come back without a doubt and do this race again. “This moment, like with everybody, I hate that it is over. “I wish we could come back and do it again,” he said. “We were laughing at ourselves when they were changing the transmission because the goal was only to finish, and then after the first laps on track, we thought ‘Maybe there’s more for us’ and over the course of the week, we started the race with the desire to win the GT race.īut the bond that had grown during the project and the pride from what NASCAR accomplished was what caught Johnson’s emotions. “We’re not the same category, but we are the same type of car, and our own estimations we thought we’d be mid-to-back pack of the GT cars and you use that for motivation,” Johnson said. Johnson couldn’t help but be disappointed. Although the systems and components on the Le Mans model are similar to the Next Gen car, the Le Mans version had functioning headlights and taillights. The lineup of Johnson, 2009 Formula One champion Jenson Button and two-time Le Mans winner Mike Rockenfeller arrived in France after more than a year of testing Garage 56 hoping only to finish the race.īut Knaus had pushed the Next Gen to its limits and the final product was heavily modified from what is currently being used in the Cup Series. Hendrick tasked Chad Knaus, winner of seven Cup championships with Johnson, to run the project and told him to spare no expense. “I hope my dad and my brother are somewhere up there looking down and smiling, but the goal when we set out was to try and finish the race running at the end and not be last. And then the way the team and the pit crews and everybody performed all week, it was just fantastic,” France said. “That was thousands of hours of hard work by hundreds of people that went into making this thing happen.
