Ford Escape / Hybrid :: 2004 - P0403 Code Came Up For EGR Solenoid
P0403 code that came up on our 2004 Escape 3.0.
Weekend before last I dropped the oil pan, cleaned it and the pickup screen out, and replaced the gasket (switching to full synthetic has been a double edged sword with the leaks that are popping up...); put in new plugs new upper intake manifold gasket and cleaned the throttle body and manifold out. All vacuum hoses inline with the EGR solenoid have also been replaced since the light went on.
While driving the following day the check engine light (CEL) came on and when checked at pep boys read P0403 (no other codes for low EGR flow, etc.). Now, the EGR solenoid is the newest non-regular maintenance item under that hood because the same code came up a couple of years ago (a new solenoid from pep boys fixed that lickety split) so I wasn't overly concerned that it had popped up again, but a bit frustrated that the solenoid only lasted as long as it did. Also, since the light popped up, I have replaced a couple of vacuum lines with some generic 4mm ID (5/32", I think) rubber vacuum hose, but that just headed off what looked like some potential future problem leaks.
Now, here I am a couple of weeks later having tried 4.5 new solenoids (Amazon sent me one with the wrong wiring harness clip so I couldn't verify that it was connected when it didn't work), and thrown some other "just in case" parts at it (new EGR valve and flow sensor, but these may be returned, but may just end up keeping them on, we'll see how things work out). I'm getting a solid reading from the hot lead on the solenoid harness at idle and during static revving, but I can't seem to get anything on the ground pin.
I've cleaned the connections and the larger pin block going into the top of the firewall to no avail. Should this read as a fluttering ground signal all the time, is it only grounded exactly when it wants the solenoid to open the EGR? What can I do to confirm that it should read grounded so I can know one way or the other whether there is a break in the line? I can't find my multimeter (or just dreamed that I picked one up last year). I'm also curious as to whether or not there's a good way to bench test the solenoid. I don't really get a reaction when I hook it up to 12v directly like I do with a vacuum solenoid from my Saab where there's an audible "click."
Is the wire harness for the solenoid a known weak spot? I've found two potential donors at the local junk yard that I can cut the wires out of to play around with/solder a new one in if that's something that the consensus deems may solve my cause. I also had an ABS light come on not too long after the CEL, but when I reset the CEL the ABS light went away and never came back (it only came on when I hit a big expansion joint on a highway bridge, no braking issues since it's been reset and ABS seems to be fully functional, per gravel road test). I still can't seem to read any ground signal at the solenoid harness at idle or with throttle input. I'd like to fix it, but don't want to start digging into the wires blind.
Ford Escape / Hybrid :: CEL Code P0403 - EGR Control Circuit Malfunction
After about 6 months I finally got the alternator replaced in the Tribute. I totally forgot about the CEL that was on for EGR Circuit. I've found a couple of pages ( OBD-II Trouble Code: P0403 Exhaust Gas Recirculation Circuit Malfunction ) that explain how to diagnose the issue but I was wondering if any other route for something that may be more common than another thing.

I'm pulling a P0403 EGR circuit fault on a 2004 v6 Escape.
Last night I changed out the EGR solenoid. Cleared the code and drove around for a while, got on the highway and cruised for a few miles and everything seemed fine. Turn the car off and back on and the code showed up again.
My next step will be to check the electrical connection to the solenoid. I don't do a lot of auto repair.
With my multimeter I will check for 12 volts. But from what I understand I can not check ground as the PCM sends ground to the solenoid to activate it. How should I check the electrical connections to the EGR solenoid?
Ford F-150 - 1997-2003 :: 2001 - Grinding Noise - Code P0403 - COPs Not Working?
2001 f150 extended cab flareside 4x4 4.6L v8, M5od manual, 196,539 miles this morning. the clutch slave is going out so I have some grinding and extra noise but recently the motor began to run like crap. I took it and coded it. "p0403, cylinder 4 misfire" is what it read on the obd scanner screen... I had a similar issue with the COPs not working and actually allowing water into the spark plug cylinder. I replaced them all at 100,000 miles or so with new motorcraft plugs at that time.
Fixed the problem and nothing since that time. Not sure why I did them all but I did. i was dumber 96000 miles ago. I also took down the intake and cleaned all the ports and crap out of it also. Yesterday took out #4 (on passenger firewall) and it looks fine. No evidence of leak, spark plug a light tan, firing well without problems, and even gaped properly still. My question is first I understood the p0403 to be EGR related, not cylinder #4 misfiring...seems odd.
2nd: I'd like to avoid just throwing parts at this problem. The EGR is simple enough to replace and if that's what is needed so be it. I'd rather do it right the first time. I've checked all of the vacuum lines, fittings, attachments. No leaks detected with smoke/brake fluid tests either. Good suction at the PCV, all good.

I have a 2007 GLS. Within the past year I had about 4 or 5 difficult starts. Just recently I got a CEL with cod P0011. I replaced the OCV as that is the usual culprit. Within 6 miles of clearing the CEL, I am still getting the same CEL. I am wondering if the problem is either the wiring harness or the Camshaft Position Sensor.

Sonata 07 CRDI 103 KW. Problem started yesterday when chek engine light came on, after a while it went of and back on. Today it went of and went to diagnosis. Diagnosis shoved fault code P0401 something with EGR.
What could cause the problem is it valve or something else?

so i just bought my '06 sonata 2.4 lt 4 cyl and it had problems with idling when i plugged into the computer i got a p0101 error code saying there was an air flow problem... took it to the dealer since it is still under warranty and for $100 they told me it was my mass air flow sensor and it would be 4 days and $370 more to replace.
I was able to buy the part from napa and replaced the old one (very simple process) and at the direction of the dealer i was told to disconnect my battery for 15 or so minutes to clear the computer data.
When i powered everything back up the car idles and runs fine but i am now getting a check engine light with p0102 lower voltage than expected from the mass airflow sensor AND a new light popped on "ESC OFF" the button will not turn it back on and i cant think of anything I did would have turned it on?
Sonata NF (2006-10) :: 2007 3.3L V6 With Intermittent Code P0018
2007 with 3.3L at 30k miles (bought new and with regular oil changes) starting throwing p0018's intermittently. No noticeable difference in way the car drives: idle seems fairly normal (only once recently felt the idle briefly stumble at a red light), fuel consumption regular, no power problems. There has been a engine tapping sound at low speeds only heard until the engine warms up after a couple of miles (I'm in Florida, temp is regular in the 70-80's), and the sound is not evident during the start-up, only while accelerating slowly.
On occasion, with hard acceleration, the "ESC 0ff" light comes on, not affected by the ESC off switch, and stays off after one key turn.
Brought to Hyundai dealer who, same day, requested doing an oil/filter change (Firestone had done a change 900 miles/3 months prior) claiming that a wrong oil filter could cause blocked oil galleys. They did the change (and also, no charge, repaired a valve cover leak) and 6 days later called to tell me the car was fine. No mention of the car having been low on oil or evidence of sludging. Also, no mention of whether or not the filter that was replaced was the incorrect filter for the vehicle. (I called Firestone and they claim they regular work with Hyundai to ensure proper filters are used). No mention of why they kept the car for an additional 5 days after the oil change before calling either (except for repairing the valve cover leak with a rocker cover gasket), and although their invoice indicated that they drove the car 5 miles, it was evident from the invoice that the mile in/miles out were the same. I did notice that there was about 2-3 gallons of fuel consumption though when I picked the car up.
6 miles from the dealer after pickup (2 key turns) CEL returns, with same code. I have now driven the car about 100 miles in the last 20 days with the CEl going off and on 4 times now, and each time the same code. I have never had the CEL come on (or go off) while driving, only at start-up. (Longest trip has been 10 miles, top speed 50mph, so a lot of key turns). The longest the CEL has stayed off was for a 30 mile span. The tapping sound mentioned above continues too.
I'm hesitating returning to the dealer. The 10 yr warranty might be a problem for a variety of reasons, and I realise finding the fix for this code could get expensive. But I do want to know what the dealer found out doing their GDS (and via eyes on inspection) and nothing was mentioned on the invoice besides the gasket leak. I'm especially concerned about the timing chain and tensioner.
Is it acceptable to make an appointment with the service manager to find out what they ruled out (and then take that information to a regular mechanic)? Given the problem is regularly intermittent over the last 100 miles, is it still possible that something might be seriously wrong with the engine and damage might be done to the engine by driving it? When I first brought the car to the dealer, they said they couldn't do anything with it because the CEL had gone out. Fortunately, within a mile from the dealer the CEL returned and they took it in. Presently, the light is out again.

View 9 RepliesSonata NF (2006-10) :: Code P0456 Won't Fully Erase And Keeps Tripping The MIL
I have a 2010 Sanata with 69500 miles. I have been getting a P0456 code for some time. I have replaced the gas cap, purge valve and the close vent valve and filter. The code still wont fully erase and keeps tripping the MIL. I have done a smoke test and there are no visible signs of leaking anywhere. What this could be.
One question I have in live data the purge valve never seems to go below 2.7 percent even when the engine is off. it was like that be for and after replacing it.
Could this all be caused by a bad ECU? I was told that in a 2010 Sanata that the ECU is common to fail. When the MIL is on I have 3 of the same code one freeze frame one that triggers the light and one that says permanent. Every time I erase the codes all but the permanent go away. No matter how many times I hit erase or even disconnect the battery it will not go away but the light shuts off.
Sonata NF (2006-10) :: Code P0300 - Multiple Misfires On 2009 V6 3.3l
I am trying to get a 2009 Sonata NF with a 3.3L V6 to run correctly and i have tried everything that i can find and still get the problem. The car runs very rich with a strong gas smell. The engine runs rough but doesn't stall. The car has has period where it runs fine and then the issue returns but is in more frequent and steady now. The car will run for the first 5 minutes great if it is cold and it also runs good at full throttle and the check engine light went off during hard acceleration which seems consistent with getting too much fuel. I bought a BlueDriver to read the codes and I love the data it provides but I am learning all the features.
For a little history the car has 95,250 miles. At 81157 miles the check engine light came on and an independent shop replaced the downstream O2 sensor and the light has been off for 2 years until coming back on recently. The code showing was a P0300. The shop replaced spark plugs and the manifold gasket with and oil change for $775. The check engine light stayed off for about a month and 550 miles. The car was taken back to the shop and they replaced the rear O2 sensor for $429 . The check engine light was off for a couple of days and then returned with the P0300. It might go a couple of days without a problem and then it would return.
This is when I got the car and started reading all the forums i could for possible causes. I saw the Tech Bulletin on the Variable Valve Timing Oil Control Solenoids so i replaced both valves. The check engine light returned with a P0303 for cylinder 3 misfire so i figured it was a coil so i replaced all the coils. The P0300 code returned. I check fuel pressure after seeing a post about fuel pressure regulators causing the problem but the pressure was correct. I changed the Mass Flow Sensor figuring it was getting too much gas but no improvement. I bought the BlueDriver so I could see more than just the codes. The O2 sensor looked erratic so i changed the front upper O2 sensor.
I found the Tech Bulletin about the O2 sensors fuel trim readings and realized there was an upper sensor on the back manifold and it was reading -18% so i changed it and now I don't know which way to go. I currently have the P0303 code confirmed and P0300 pending. With the live data the items that looked strange at idle were O2 Sensor Bank 1 Sensor 2 steady at 99.2% and Calculated Engine Load a 21.6%. The freeze frame data from when the light came on has all the short fuel trim at 0.0% and long term at -0.8% for both banks. Calculated Engine Load was 45.9% even though I was trying to drive slowly at 29 mph. Mass Air was 21.71 g/s, I had been running 3 minutes from a slightly warm start, Absolute engine load was 44.3%. Anything else to check or data I should look at?

Have got a 2006 Azera 3.3 (same engine as Sonata and have had no luck in the Azera section) which is showing Check Engine Light and P0171 code. Have cleared it but it soon returns and emissions are very high. I have tried with my limited knowledge to check the live data via a scanner but everything seems OK.
I've cleaned the MAF sensor but I'm thinking of replacing it but don't want to do this unnecessarily!
Is there anything else I could be checking? Car drives OK and there's nothing obvious symptom wise other than the emissions and the CEL.
