2016 Tacoma TRD Power Loss, Bucking, and Fuel System Codes - Need Help!

Hey everyone,

I was driving my 2016 Tacoma TRD to a buddy's house when I started to experience power loss and bucking while going down the highway. My check engine light and "TRAC OFF" light came on. After pulling over, I scanned the truck with an OBD-II reader and got the following codes:

• P0087 - Fuel Rail/System Pressure Too Low
• P107B - Fuel Pressure Sensor Rationality (Low)
• P0171 - System Too Lean (Bank 1)
• P0174 - System Too Lean (Bank 2)

I was under a quarter tank of gas at the time, and I could still drive to my buddy’s place by accelerating gradually, but I couldn’t go over 50-60 km/h.

The next morning, I added 5 liters of fuel from a jerry can, reset the codes, and managed to drive about 20 kilometers without issues before the bucking and stuttering started again. I made it to a gas station, filled the tank completely, and reset the codes again. Since then, I’ve been driving for a couple of hours with no more issues, although the codes are still present when I check with my OBD-II scanner.

Has anyone experienced something similar or have any ideas about what could be going on? Any suggestions are appreciated!

 

Did your truck require the low pressure fuel pump recall? If so was it done?

 

Sounds like you were out of gas, certainly not uncommon for the gauge to be less than accurate as the truck ages.

 

So I filled my tank and reset the codes and drove for 2 weeks in the city with no problems at all. The codes didnt come back on until I drove down the highway tonight and the same thing happened again. Truck started losing power at half a tank so I do not think I was out of gas. What could this be?

 

Have you kept track of mileage instead of using the gauge? 2 weeks on a tank of gas sounds like alot unless you aren't driving much.

There really only seems like 2 logical possibilities here, either your fuel gauge is wrong and your running it out of gas or you have an issue with the low or high pressure fuel pump causing low fuel pressure.

The inaccurate fuel gauge would be relatively easy to rule out, just keep track of your mileage and go by miles driven to fill up instead of relying on the gauge. If you no longer have the issue then your gauge isn't reading right, if you still have the issue despite making certain there is sufficient fuel in the tank then further diagnosis of the fuel system will need to be done.

 

I have a 2019 TRD OR DCLB, same identical issue, took it in to the dealer, did the fuel pump replacement (recall) 6.5k miles later, zero issues ....Tacoma is happy.
