For the longest time my cars fuel sending units have been pretty much dead so my gas Guage doesn't work. As well today I got 3 different engine codes all at once 2 for the fuel sending units something to do with the voltage And one for the throttle body, my biggest issue is it keeps throwing my car into limp mode so I have to delete the code and restart my car several times to get it out of limp mood. Which it drives fine when it's not in limp mode but it kept sending it back into Lm.
Is it possible the fuel sending units malfunction is messing with the function of the tps or something else that messing with both the electronics of the sensors.
Or is it the old age of my car showing it stripes
The codes are p2135 p0463

 

Google the codes #1 then find their main causes.

Its my experience that in modern cars when a major sensor fails, it tends to fool or give bad feedback to the ECM. And the ECM starts acting retarted, and sends ur car to limpMode.
Also, sometimes the ECM can send WRONG codes due to bad interpretation of the damaged parts. SO do your homework B4 you start changing parts.

If you KNOW the fuel sending units are bad, change them. Chances are they may be messing with the TPS or the ECM, you never know how how ECM desides to diagnose the car.

GL!

 

I know all the symptoms of each code. I'm just more worried about trying to dignose the real issue without going to the dealer. Weather it's just the fuel sending units or both the the fuel units and tps have gone bad. Like you said just because it's diagnosed one way by the ecu doesn't mean it's the actuall problem.

 

Well if you have the equipment, try testing the fuel PSI for starters. Your key is that the car chugs when hot. hmm...keep searching ...
