I have a Check Engine light and the code it's throwing is Reductant B Heater. I showed up at 8 and had the truck back at 10:30. If any issues are found during this procedure, they would be relayed over to the customer to make a repair decision. Dan, Thanks for sharing and congrats on a great outcome. Unplug and replug some connectors, reset the code and go.
Reconnect the injector nozzle and connector. This story just has too good an ending to not share. We'll remove all of these with 13 millimeter socket and ratchet as well as various extensions as necessary. Common mistakes when diagnosing the P2043 code A common mistake that can be made when diagnosing this trouble code would be replacing an oxygen sensor instead of replacing the exhaust temperature sensor. What repairs can fix the P2043 code? International buyers please note: First class mail may take up to 30 or more days and is not trackable.
They told me it was backordered nationally, so they didn't have a projected date when it would arrive. Remove that with a socket ratchet and some extensions. What are the causes of the P2043 code? It is recommended to have this trouble code diagnosed and repaired as soon as possible. Pull the filler neck down and through. You can now tighten down all the 13-millimeter hardware with the socket, ratchet, and extension.
Then lower the skid plate and slide it out of the way. These little metal clips can be meddlesome. There are two bolts here at the front, a nut just about flush with the rear cab mount, another bolt tucked up in here just after the leaf spring perch, and all the way at the back closest to the axle, there's another nut. Let that hang out of the way. But the solution seems to be to replace the part that's generating the error.
This is on the driver's side of the skid plate. . Ford has not been able to find anything wrong. Set the new gasket down and around the outside edge of your heater. I'm now going to remove myself out from under it. Once that's in, I'm going to slide under it and install bolts on the other side to keep it level and in place. The sensor can't be replaced separately from the tank.
Now I call that a pretty good outcome. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Lock the new connector back onto its tab. Once you've unscrewed the lock ring, pull the harness through, peel the gasket out, remove that as well. What was the part that was the culprit? So you'll see in the bottom of the tank the notches that this heater module sits into.
You may have to before you can post: click the register link above to proceed. How does a mechanic diagnose the P2043 code? They called back the next day and said the part should arrive at the dealership by Monday or Tuesday. I have had no ill-effects but am worried now that I can't trust the Check Engine light system if the light stays on all the time. This trouble code is moderately serious. Less than an hour later I got another message. The engine will not be able to breathe efficiently with this code stored in the powertrain control module.
I think there is a heater involved along with a temperature sensor so that the vehicle can work properly in below-freezing temps. We have a ton more information on this and many other vehicles. When you're out, speed gets limited to 4mph. We just want to make sure that we have plenty of slack when we remove our harness. Be careful of your filler lines coming over top the frame as well.
