Here’s how to detect low transmission fluid signs. This is a common cause of not accelerating, but the RPM rises.īefore the transmission ran out of fluid, you should have noticed the RPM going up too fast for the speed you were going, indicating that the transmission fluid was low. You should check the transmission fluid immediately. The power goes to the torque converter, and that’s the end of the line. If your Pathfinder is too low on transmission fluid, it will no longer be able to transfer power to the wheels. Look for a red puddle under where you’ve been parking your vehicle. The engine should sound completely normal. It should still move some though, if it’s the cause. While the ignition system is the most likely reason a vehicle won’t accelerate as fast as it should. A spark plug wire goes bad when it can no longer transfer the spark from the coil pack or distributor properly.

Plug Wires– Spark plug wires are not as common as they used to be, but your particular model of Pathfinder may have them, so they are on the list.

When one has gone bad, they’ll usually cause your Pathfinder to accelerate slowly, idle rough, and will hurt fuel mileage.

Coil Packs– Your ignition coil, or coil packs, create the spark and send it to the spark plug at just the right time for optimal power and efficiency.

Oil on the plugs, the wrong or bad spark plugs can cause a misfire.

Spark Plugs– Even under the best conditions, spark plugs will eventually need to be replaced.

A misfire is the most common reason your Nissan Pathfinder isn’t accelerating. But, more often than not, it’s going to be the spark plugs or coil packs that are the culprit.

You should be able to hear it, and it’ll likely be paired with a code such as P0300 or P030X (where X is the misfiring cylinder).Ī few things can cause an engine to misfire. Here are the most common cause of acceleration with the RPMs going up: Misfire This is typically an issue related to the transmission Somehow, your engine’s power is not making it to the rear wheels. If your Pathfinder doesn’t accelerate, but the RPMs go up, it’s usually not an engine-related issue.

Nissan Pathfinder Won’t Accelerate Causes The check engine light should almost always accompany those. We’ve made a table to help you try and narrow them down before reading through all of this.Īs you can see above, there are only a few reasons why a vehicle won’t accelerate at all. There are so many reasons your Pathfinder won’t accelerate. May limp, or there’ll be no acceleration at all. You’ll likely get P0171 with the check engine light.

The engine should stall out when trying to accelerate. It may be making a whining noise coming from the vehicle’s rear. It should stall out when giving it more gas. There may be a rotten smell coming from the exhaust pipe. It may feel like it has a hard limit to how much gas you can give it. Usually, the vehicle’s transmission will slip before there’s no acceleration. You may hear a slapping sound when you put the vehicle in gear.

You should smell a rotten smell when the clutch is burning up. It should start out slipping, and then eventually no movement There may be a burning or sweet smell coming from under the hood. You should hear the misfire when revving the engine when the vehicle is parked. Start with whatever parts of the vehicle the codes indicate are having a problem. If your vehicle’s check engine light is on, there’s valuable info stored in there. Most problems significant enough to make your Nissan Pathfinder not accelerate will cause a diagnostic trouble code. We’ve put a quick information table to help you determine why your Pathfinder won’t accelerate. There’s a lot of information here, and it can be overwhelming. They can provide valuable insight as to what the problem may be and help you narrow down the problem.

If your check engine light is on, get a code scanner and see what trouble codes are stored in the PCM (powertrain control module). If your Nissan Pathfinder won’t accelerate, that is a serious cause for concern.
