Santa Fe (CM - 2007-12) :: Greyed Out Fault Codes - C2820 / P2019 And U1904
May 7, 2016
2007 Hyundai Santa Fe Limited, 3.3l engine, 2wd, about 110k miles
I recently replaced my neutral safety switch, but wasn't able to run codes at that time. The fuel level sensors need to be replaced, but haven't gotten to it yet. The usual P0463, P2068, and P0464 codes are active.
The following greyed out codes came up in a scan, and I searched this forum (and google) and found little info.
Mystery greyed out codes are: C2820, P2019, U1904.
Codes were reset with no problem...

As far as trouble shooting faults in the ABS - does it store fault codes and how can they be read ?
Daughter's 2007 Elantra has ABS symbol lit for a week, I took it to a car wash and used the high pressure spray to clean the wheel hub areas and that may have fixed the problem but interested if ABS fault codes are stored and can be read.

I've been having P0441 & P0455 codes showing up on my 2007 Corolla CE. My code reader tells me the areas that need checked. But, I can't find the vacuum switching valve on it so that I can check it for problems. Somebody said it's under the hood, but I can't seem to locate it.
Is is possible that it's mounted on the vapor canister (which I have located above the rear axle)?

I took my 2009 Santa Fe Limited in to Firesteone last Friday. After the oil change and alignment, I drove out without any issues. Current mileage is 61k+.
I was running some other errands and drove about 20 miles to the next destination and parked. Came back within 45 mins and started the car when 2 lights came up on the dash - malfunction indicator lamp and engine oil pressure warning light.
I called the Firestone service center who suggested another location closer to my current position. The guy at the other location checked the error codes with the scanner which came up with P0021 and P0022.
Now, I am not very handy with anything car related and my vehicle is just out of factory warranty by 3 months and 1200 miles. I am concerned that these error codes point to expensive repairs.
Are these issues common in my model? The car seems to run fine. Could this only be the sensors or oil valves?
Assuming the worst case scenario, how long should I be able to drive before immediate need for repairs or without making the issue worse?

My wife has a 09 Santa Fe and we were getting code p0464 fuel sensor circuit intermittent. I changed both parts that need replacing. After about 20 miles now code p0442 small evap leak detected. I can only assume that it is coming from the fuel sensors that were replaced. Is there anything that I could have screwed up on?

My 2008 just showed the light at 108,000 kms. Its a long drive to the dealers. My old Hondas would flash a code number in the instrument cluster if I shorted out a pin under the dash. Is there a way to do this with the Fe?

My 07 3.3 SF is throwing P0154 and P0300 codes. Autozone said the P0154 is Bank 2 pre-cat O2 sensor. But exactly which one? The P0300 is random misfire. Could they be related?

I have been having this same problem over and over again. Check engine light comes on with P2127 and P2106 codes. 1st time they said they needed to flash the computer. Worked fine for maybe 6 months and then again. While this is happening you cant go over 2500 rmp with it floored and takes forever to get up to 60-80 kph which is the fastest it will go. Sometimes after starting stopping 5-8 times it will be fine. The second time they replaced the gas pedal because the sensor was deemed bad. Now about 8 months later here up it comes again. This time I was pulling my boat and I thought I wasn't going to make it up the hill. I don't trust this car anymore especially for long trips. So anyway they updated the computer again, and then 4 days later up it comes again. Also inner tie rod ends I have replaced 3, just so you know I only have 52000 kms on this 2008.

I have the 2011 Santa Fe V6 and it has the P0447 & P0455 codes popping up on my reader. I checked the pins to make sure that there is voltage getting to the solenoid, (about 11volts at the 2 pins) and it seems good. No fuel lines broken, or cap messed up, etc.

2 error codes? Car runs fine - nothing seems wrong - the check engine light went on, so I pulled out the scanner which came up with the 2 codes: P0021 and P0022.

So a couple days ago i replaced the fuel level sensors in my 07 gls 2.7 liter santa fe and all was well for 2 days. I had finally driven it enough that the codes cleared from active status and the car turned off the cel. However, during the same ignition cycle the engine started missing a bit and the cel came back on and started flashing at me. Codes found now are p2187 lean bank one and p2189 lean bank two, plus p0302 misfire detected cyl 2. I've tried the carb cleaner trick looking for a vacuum leak.. but no luck. Air intake boot is good vacuum lines look good etc. What might be going on? Did i get debris in the tank and glog an injector with it? Fuel pump itself appears to be operational. No bogging down or loss of power under heavy acceleration.

We have a 2006 CM later model Santa Fe 2.2 CDX+ 7 seater. Engine light came on last week and since then car does not shift into 4th gear. It revs very high upto 5000rpm with no increase in speed, it's limited to 30-35mph.
I had this problem back in 2010 where the Hyundai franchise identified a fault with the EGR which was replaced under warranty, and then a year later a problem with the fuel sensor which was also replaced.
I had the local garage check the EGR and give it a clean based on the steps provided by a member here - no change. So I took it to Hyundai but this time, they are reporting fault codes P0733 and P0744 which point to transmission problems. I just had a call from the garage who say they believe the gear synchromesh is jamming thus not allowing the change of gears. He said that the diagnostics report that the car is sending the gear change command correctly (pulse generator ok) so does not believe it is an electrical fault.

My wifes 2007 Santa Fe Limited 3.3 has had a check engine light going on a year now. Car has about 122k on it now. Scanned codes about 6 months ago and had a fuel system lean code. Did some reading and ended up replacing the purge valve. The CEL stayed off til the end of the drive cycle and came right back. I have noticed when you fill the car up there is a real strong smell of gas but the car always starts right up. It now has a P0171 Fuel system too lean (b1) and P2187 Fuel system too lean at idle. Where to start. Don't have much background with hyundai. Also the ESC off light comes on randomly and goes off. Doesn't happen real frequently though.

Can dealership diagnostic tools read ABS/ASR fault codes, or if those codes are even stored?

So i installed a USP test pipe and got Revo Stage 2 upgrade yesterday. I had no codes before the test pipe. I still have a CEL for 9 fault codes. 4 of which are all the o2 sensor codes. With all these codes my Traction Control light is on too. I think this may be a safety thing. I thought Stage 2 was supposed to get rid of the CEL. Especially for the 02 sensors in the rear.

I coded a few things through VCDS (fogs as DRLs, turned up XDS, enabled TSC, etc.) and now I'm getting fault codes from ABS...
I did an autoscan before I started and there were no fault codes before.

These warning lights are lit but my code reader (Actron CP9180) shows 'pass' meaning no fault codes. I had a similar thing happen about a year ago Before I had my own reader) and the cause was a faulty speed sensor on one wheel. Since then all 4 hubs have been replaced. Does this sound like the brake module?

I was told that these are affiliated to a problem with the air pump (not the one you pump the tire up with) -- Need to locate the air pump? Hoping to find a loose hose or something I can fix.

All seems to be going well, drove the car for first 200 meters yesterday! Replacing the faulty parts is always easiest, just need to know if there are any shortcuts for fixing this. What's the engine oil temperature sensor? The one bolted in oil pan?
The intake air temperature is showing -40 degrees celsius.
MAF is plugged correctly.
VAG-COM gives me these following codes:
3 Faults Found:
000406 - Engine Oil Temp. Sensor (G8)
P0196 - 004 - Implausible Signal - Intermittent
000275 - Intake Air Temp. Sensor (G42)
P0113 - 002 - Signal too High - Intermittent
000258 - Mass Air Flow Sensor (G70)
P0102 - 002 - Signal too Low
Readiness: 0000 0000
