I’ve always been one to do my own work instead of dealing with shops charging a fortune for easy repairs.
I have had a lot of problems out my 2011 Sonata and I can’t quite figure out what the cause is.
About 6 months ago, I had to replace my MAP sensor (Barometric Pressure Sensor) due to it going out, as well as my power steering coupler.
When I replaced the MAP Sensor all went well and it was running smoothly. I replaced the coupler and ran into an issue when taking off my steering wheel. My air bag clock spring came unwound. Shortly after, my fuel level sensor, as well as my brake light switch went out. So within the past two weeks… I have replaced the clock spring, the fuel level sensor and the brake light switch. Now that all of that and said and done…
My fuel level sensor still does not work after replacement
Traction control light is always on saying I have no traction
Reverse lights went out like 2 days ago, both at the same time, I haven’t checked yet, but I believe it’s a fuse.
Check engine light came on yesterday, I used my OBD Scanner and pulled these codes:
P2110 - “Engine Performance - What the code definition basically means is that the vehicle has been forced into a “limp in condition”. Engine RPM’s are reduced to the point of the engine running just above idle so that the vehicle can be “limped in” to a repair facility or off the road into a parking lot, etc. without doing any further damage to it. The problem is usually with the vehicle’s transmission or one of the sensors that control it. Some examples are the Throttle Actuator Control (TAC) motor stuck, faulty TAC control, TAC wiring or connection problems to name a few. The vehicle should be taken to a professional automotive repair facility for an in-depth diagnosis.”
P0605 - Internal Control Module Read Memory (ROM) Error (I don’t have much information for this one)
P0106 - “Engine Performance - The Manifold Absolute Pressure/Barometric Pressure Circuit measures the air pressure inside of the intake manifold. If there is too little or too much air pressure, this sensor sends a signal to the vehicle’s computer which in turn makes adjustments to the air/fuel mixture, along with other adjustments, to keep the engine running smoothly. This sensor directly affects vehicle emissions. If the signal that is sent to the computer is compromised in any way, it will turn on the Check Engine Light and this code will set. A lack of engine performance will be noticed. A visit to a qualified repair facility for further diagnosis is recommended to repair this problem.”
P0463 - “Emission Controls - The Fuel Level Sensor is part of the Fuel Level Sensor Unit that is located inside of the fuel tank. As the Fuel Level Sensor float moves up and down with the level of fuel in the fuel tank, an electrical signal is created and sent to the vehicle’s computer which then creates its own signal to the fuel gauge which in turn shows the proper amount of fuel in the fuel tank. If too high of a voltage signal is sent to the computer it relates to an incorrect fuel level reading. Once this incorrect reading is recognized by the vehicle’s computer, it will turn on the Check Engine Light and set this trouble code. Due to the number of items that play into setting this code, a more detailed diagnosis will need to be performed at a reputable repair facility.”
I tried to start my car yesterday and it refuses to crank, which I believe comes down to the MAP Sensor messing with the Fuel Pump.
So I have come to this conclusion:
MAP Sensor is out again. (I believe this caused P0106 and P2110)
Fuel sensor still not working. (P0463)
Reverse lights I believe is a fuse, I have yet to check.
Traction Control Light stays on… (I thought this was the brake light switch causing this, but after replacement, it still stays on.)
I think a lot of this is coming down to my PCM crapping out on me, but I’m not 100% sure. I am stubborn about taking my car to the dealership but I think it’s about to come to that.
Does anyone have any idea what is going on?
