Santa FE SM (2001-06) :: 2002 - Engine Running Flat Under Load
Apr 22, 2015
Those are the codes I'm getting. P0340, P1166 and P1167
Here's the story. Engine running flat under load. Easy acceleration is ok, but merging onto the turnpike causes a noticeable loss of power. Replaced the cam sensor, cleared the codes, ran ok for a day. Same codes came back, same flat performance.
Returned the cam sensor with another new one to make sure it wasn't a dud out of the box. Advance Auto Parts is awesome - replaced it no questions asked.
Installed the new cam sensor, cleared the codes. Ran great for a day, then the same symptoms came back, with the same codes. I'm thinking it might be the ECU? If it is, how expensive are they? And do they have to be programmed by the dealer?
This is a 2002 Santa Fe 2.7l automatic with around 147k miles on it.

My Santa Fe driving me crazy. Have a 2002 Santa Fe 4 cyl with a problem. It will start when cold and run normal about 2 minutes. Then it starts running erratically like a misfire. If you let it idle this way it will stall quickly and not restart until totally cold again the next day. If you catch it quick enough and continually pump the throttle it continues to run rough until it starts to warm up. As it warms up the engine slowly improves until it reaches operating temp. At this point the misfire is much less but still there. If you shut it off for more than 10 minutes it will not start until the next day. There are no codes at this time. I have changed the coolant temp. sensor, the cam position sensor, fuel pump and screen, spark plugs and wires. I have also verified all timing marks on the crank, cams, etc. The crank sensor was replaced about 40k ago when the timing belt was replaced. What can I look for now???

02 v6 awd my power steering cooler had a leak and was spraying fluid all over radiator. I replaced it and did a coolant flush new thermostat and a new temp sensor. Was still getting hot gauge was touching bottom of red. Did some looking my ac wasn't working for some reason the fuse was loose. I pushed it in and the big fan instantly kicked on high along with the ac. The small fan on the front of the condenser isn't running. Could this be my problem? When is it supposed to be running? I swapped the relays around with no change. I might take it apart tomorrow and hardware fan to see if it shot craps.

This little engine runs very hot. To make matters worst the radiator fan comes on high on the gauge temperature reading unlike other cars I have had in the past. What else to do to run the engine cooler without affecting fuel economy? I wish there was a way to make the radiator fan come on at a lower temperature.

I have a 2002 Santa Fe V6. I'm getting the codes p1529, p0755, p0760, & p0765.
The car can start up & go, only for a short time. Engine will keep running, car won't move.
Kill the engine for 3 to 5 minutes, can start it up & go once again. Going 40mph increases the odds of the car not moving quicker.

I have an 02 Venture WB Package with the 3400 engine. Within the last week is has started to run rough under load. This happens mainly when it is driving, but it does happen at idle when there is an incline or decline.
A little background of what happened. It has not wanted to start all of the time and i heard that it might be a dirty MAF. Well, the MAF is clean and still not wanted to start all or the time. During this time I noticed a plastic line going from the intake tube into the rear valve cover was loose, so I thought this was the problem. I have big hands and couldn't reach the rear vavle cover without rocking the engine forward. When I finally got the bolts out of the mounts that attache to the engine, the engine rocked back a little. I didn't think anything of this and ratchet strapped the engine forward so i could reach the valve cover.
I got the line back in and put the engine back where it is supposed to go and all was well. A few days after doing this my wife told me the van was running rough so i took it for a spin and she was correct. It is hard to describe the sound it makes, but it almost sounds like there is was too much stress on the engine when I have the gas peddle pressed. The van doesn't lose any power i don't think. The van sounds great if it is coasting.
It only does this when there is a load on the engine in drive or if it is idle or parked on an incline or decline. It goes into the shop on thursday the 30th, but I would rather not spend the cash if i can do it myself. I am totally lost with this one. I have a video of the sound when I am driving it, but the sound isn't too loud on the video.

I have an odd one; there's a noise that sounds like an consistent electrical snapping noise coming from the engine while running. Everything seems fine otherwise. Just looking for possible things to check.

When firing up the engine cold it runs really rough, smells very rich all the time, even warmed up. No codes set, fuel trims are within 5-10%. I've replaced the front O2 sensor, swapped crank & cam sensors, Map sensor (have lots of spare parts) & I'm sure there was more things I've changed but can't remember. I have a snap on scanner and everything is within parameters.
I have not checked the EGR valve or solenoids yet. It's a 2006 Santa Fe 2.4l 5 speed, new timing belt & balance belt replaced when I dropped this engine in. Is there a common problem with these that I could begin looking for?

Recently replaced plugs/wires on soon-to-be 10 year old '04 SF 3.5L (157K mi.) for the first time.
Plugs were OE Champion Platinum and all 6 looked identical except for excessive gap of .010 +/- due to all the miles. Replaced plugs with same as OE. Old plug wires looked good, but replaced them with aftermarket wires ( fit was as good as OE). Also replaced plenum gasket.
Problem is: engine runs rough at idle and high rpm and appears to be mis-firing. CEL is off and code reader shows no Trouble Codes stored.

I recently replaced timing belt and balance belt on my 2004 santa fe 2.4l and now the engine runs like crap and shakes badly. I went over all timing marks again and again and I am at a loss.

Looking for a picture/location etc of where the crank position sensor is in the engine compartment? It seems to be a common issue where the engine stalls during driving and you pull over and are able to restart the vehicle and go on about your business.
My 02 has over 160k in miles and so am believing this part is going out according to what I've read here. My problem before was somehow the 2wire plug to the alternator worked it's way off and got that taken care of and so now while my wife is driving, it'll occasionally stall. Did a load test on the battery and it's good. Didn't check the charging system but not sure it needs to be tested.
By the way, have ran the diagnostics with the actron pocket obdII and no error codes came up and all looked good scrolling through everything.

2002 2.7L. Engine seized. Bought a replacement also from a 2002. Tried to start today and no spark. I just replaced the physically broken crank position sensor. That seemed like it would be an obvious and easy fix, but still no spark. The broken sensor had frayed/shorted wires. Could that have damaged the PCM /ECU? There is a 2003 Santa Fe at U-Pull-It that was running when it came in. Will the PCM from that work? I am running out of time. I have to have this running before I leave on a flight tomorrow night. I do have a code reader (if I can find it) but I can't imaging it would have any codes if it hasn't started since I had the battery out. Not sure how that works.

I am struggling to find out any information regarding a droning noise coming from my engine. It generally does it when its just ticking over and disappears when accelerating.

2002 hyundai santa fe GL2 4 Cyl Automatic ... I noticed that there is a super heavy motorcycle-ish loud noise from my engine when I put it in drive. When it's idle or in reverse or neutral the problem does not occur. but then when I switch it to drive, uber loud noise...which gets louder when I step on the gas.
What has been done so far - replaced spark plugs, ignition coils and plug wires so far...also changed the oil, no fix.
No check engine light at all.....however the battery did die due to someone leaving a light on for days So I am unable to get any code readings.

Its a 2002 Santa Fe 2.0 turbo diesel. When driving the engine will suddenly cut out. Its as though the ignition has been turned off, there is no hesitation or warning, it just shuts down.
This is what has been done so far: New high pressure fuel pump fitted by main dealer in June. My mechanic has fitted a new high pressure fuel sensor, new low pressure fuel pump (at rear by fuel tank), changed relays around, checked all fuel injectors (found in good condition) and checked various connection plugs and wiring. At motorway speeds the engine will not cut, its only at lower speeds. When it cuts the EML comes on with a 'Fuel Pressure Fault' code. Sometimes the light doesn't come on. Sometimes the light comes on but will go out the next day. When the engine cuts out you have to wait 20 seconds before it will re-start. If you try to start before this the engine will only turn over without firing. The car has only done 79000 miles. The main dealer gave up and said they don't know where the fault is because the code is not specific enough.

My 2002 Hyundai Santa Fe 2.7L V6 AWD failed to start a week ago. After towing to my neighborhood repair shop, it was diagnosed as a faulty ECM based on code P560 (System Voltage Problem). They replaced the ECM (along with relay) with a used one with the exact same part#. After that, the car was started and run OK but Check Engine Light stays on all the time. The codes displayed are:
P1529 TCU MIL Request Signal
P0501 VSS Range Performance
I was told that this is caused by the fact that each ECM is VIN/PIN locked. The replacing ECM was used in another car before and was locked with a different VIN thus cannot communicate with some components of the current car.
My questions are:
Can this used ECM be unlocked and relocked with a new VIN/PIN? If so, does it require the previous VIN/PIN to unlock? Most likely the previous VIN/PIN is no longer available.
Does this service require the presence of the car or can it be done with the ECM alone? Do keys need to be re-registered? The car starts fine currently.

Question about my 2012 Hyundai Santa Fe SE. The car has 25,000 miles on it, and just recently like in the last 1,000 miles I have notice when I use the AC, or even the air without the AC the engine reacts very poorly like it is under extremely heavy load. The car shakes and vibrates.
I completely understand that in AC mode, the compressor kicks in, but this to me seems excessive. The car vibrates and the idle drops substantially. AC on is worse that no AC.
In addition, idle or under 35 is worse that HWY driving. The vibration is so pronounced that I sometimes wont turn the AC or air on as the vehicle feels like it is going to rip itself apart.
This is something new and never vibrated this much before the 25,000 miles. Anything I should look into or have the Hyundai Dealer look into? What I may be over looking? Would more stout battery work?

2002 Toyota Sienna wobbles when engine under load and is more noticeable at certain speeds (like around 40 mph). The wobble is lateral in the body of the car and the steering wheel IS NOT vibrating.AutoMD web site suggests it may be the motor mounts. I did their diagnostic suggestion of putting the car in gear with the emergency brake on and foot on brake .. and revving the engine and letting up. I didn't notice a "knock" when the torque was released on the engine.My local mechanic is stymied ... says he checked the motor mounts, and front end mechanics and they are OK ...
