Santa FE SM (2001-06) :: 2003 2.7L Engine Failed To Start / Puddle Splash Caused A Short
Aug 20, 2014
This concerns a 2003 Hyundai Santa Fe 2.7L engine.
Bad rain, combined with a puddle splash caused a short (someplace). Vehicle ran poorly on way home and then eventually failed to start. Replaced the Cam Position Sensor and the Crankshaft Position Sensor. Checked all wiring and connections. Cleared codes and the vehicle started. Ran for about 15/20 minutes and a P0340 code popped with the engine light on. Car still runs fine. Researched code and learned that this code is a Camshaft Position Sensor A - Circuit Malfunction.
1. Bad ground in Circuit.
2. Open Circuit that fails to close.
3. PCM malfunction.
Questions:
1. Where in this vehicles is the PCM located? Is it within the main ECU in one of the other ECU fuses or an independent fuse?
2. Other than the 3 issues listed above, could I be overlooking anything else?

Need to get to ATF drain plug, but have engine splash shield in the way. Any step by step? Will I need to get this thing on stands/jacks to do this?

I have an issue for the last couple of years. I drive a 2006 hyundai santa fe with 168,000 km's on it. the problem I am having only happens on any cold day and never above zero celcius and when I start the vehicle on a cold day and go for a short trip to the store run in for about 5-10 minutes and I come back out and it won't start, there is lots of power but it wont roll over at all but after trying many times it will eventually start and there is no CEL showing and I have never plugged it in on a cold day and as cold as the canadian winters get here its been down to as low as -40 in the morning and no problems at all, a little roll and a groan and away she goes which is typical in our cold climates.

We are at 120K miles. The vehicle runs fine most of the time, but every once in 10-15 starts, it will rough idle or stall after a short warm up time when my wife stops at an intersection. Once she restarts it, it runs fine.
I have changed the spark plugs and wires, the fuel pump, the crankshaft position sensor (was fried) and after consulting this forum, I checked the fuel pressure regulator and the diaphragm is not leaking.
I was able to recreate the rough idle and the CEL on the dash, but my two OBDII readers said there were no codes And the bluetooth reader I am using is indicating that the following tests are not completing: Fuel System, Catalyst, Evaporative System and Oxygen Senors.
The dash CEL resets itself upon restart and does not light until the symptoms return.
After reading the Haynes Repair Manual, I am wondering about the Evaporative Emissions Control (EVAP) system? But I don't want to lead the troubleshooting.
We bought the vehicle at 60K miles and it has been mostly reliable.

We recently changed the timing belt & serpentine belt & new alternator. Drove great for 2 days. Then car would stall out when idling, had rough idle. We replaced the Crankshaft position sensor (got one from the dealer) & the electrical connector. The engine cranks but won't start. The only code we're getting is P0335. We've checked all the fuses. Fuel pump starts when turning on the key. We've been a week without a car and trying to come up with something.

My wifes 2004 Santa Fe has no heat. From what I have read, a common cause of this is the blend door. I pulled the glove box, but was unable to locate the blend door. On the parts diagram it appears to be on the bottom of the heater box. Every tutorial I have seen show it on the right side, and easily accessible.

I have a 2005 Santa Fe which I brought brand new in 2005. After 48,000 the transmission was shot, the fluid was black it was a mess. I had the tranny serviced at about 30,000 miles and thought everything was ok. My dealer replaced the tranny under warranty and said it failed, thats it. Ok.....64,000 miles later the second transmission just failed. Keep in mind the dealer serviced the transmission twice and now this one is shot. Being out of warranty, Hyundai wants me to pay for a new one, I opted to get it rebuilt at a local shop. My question is other that why aren't these transmissions lasting, am I alone or this quite common.

I have a 2004 Santa fe and if it is raining or if I drive through a puddle of water, my steering is locking up, what may be causing it? I am afraid it will cause me to wreck.

I have a strange problem with my 2001 Santa Fe GLS that I can't put a finger on.
With my AC running, whenever the condenser fan (the one on the driver side) comes on, the electrical system seems to short out briefly (1/2 sec) - all lights go dimmed, the vehicle bucks - very scary when driving. Sometimes the engine sometimes shut off if idling.
I've changed the AC compressor (twice) and changed the entire condenser fan assembly to no avail.

2003 PT Cruiser won't start immediately after short trip with a short stop. Always does start after turning the key and holding it to start position. The check engine light is often on and the code is for a cam shaft sensor or resistor sensor. A companion problem is the cruise control. If the check engine light is OFF and I use the cruise control, it works fine for a while and then the check engine light comes on at the same instant the cruise control turns off. Are these 2 issues connected? How much should it cost to have the sensor replaced? The car always stays running once it starts and the problem occurs randomly. What are the consequences of not repairing it?

We have a Hyundai Santa Fe 2003 2.7 V6 and sometimes it just won't start, the starter motor turns over fine and the battery is fully charged, and most other times it starts straight away. The engine purrs nicely when it's running.
I suspect it's an electrical fault, perhaps a faulty sensor? (Cam position sensor, crank position sensor, fuel position sensor?) What sensor would cause the car to start and run perfectly some times and not start at all other times?
Immobilser issue? Although I don't have a button on my key so maybe the car doesn't have one.

Mon. Dec. 12 Cincinnati had record 1.95" rain. I hit a puddle (which I later found out was 1' deep) with my 2011 TDI. A wave of water came up over hood & turbocharger sucked it into the engine. Stalled out, wouldn't restart. Towed to dealer, they said have to replace engine. Ins. Adjuster saw that, other water damage, totaled car. Santa gave me a 2012 red Golf TDI.

Two times in the last month my 2003 Sante Fe would not start - the radio, air conditioning will come on but nothing from the engine - not even a click - no check engine light. Had it towed both times - as soon as it was towed it would start up. It seems to happen in 2 week intervals. Now I realize bc they had it in neutral to get on the truck that is what required to start. It hasn't happened in a week but I know it will again.

The past couple weeks, my '03 Santa Fe 2.7 has begun to grind a while before starting -especially when weather is hot and has been sitting a while. Once it starts, all is normal. Most of the time it starts right up -no problem. This just happens once in a while. Slowly, it seems to be getting worse. I replaced battery -no change. ...................???

My 2007 Passat Wagon has a weird problem. Sometimes, it failed to start engine. The only signal on the panel is the red battery sign. I need to reinsert the key and try again. It does not happen every time.

I just replaced the motor in a 2002 Sante Fe 2.7 due to timing belt breaking, this motor will not start, it turns over, but I am getting no fire to the coils. Crank sensor replaced waiting on the cam sensor, anything else it could be?

I am having serious problems with my 2003 Santa Fe 2WD 2.7. First, about two months ago, I would have typical crankshaft position sensor problems whenever it would rain outside and my car would not start or if it did it would eventually stall while driving. Before stalling, the engine light would come on with code P0335 and the engine would shake. I did my best not to drive it during these moments and was always able to get it back home. The problem went away after a couple days of issues until recently.
About a week ago, the P0335 code came back with associated symptoms; however, this time it would not go away. It is worth noting however that I am in Portland Oregon and it is raining non-stop this time of the year. I am not a mechanic, but my neighbor used to be and he carefully guided me through replacing my Crankshaft Position Sensor, Camshaft Position Sensor, and several spark plugs.
After all of this work, my car turns over and starts for maybe a second, where before it would not even fully turn over in my driveway. It immediately dies after the second and then I can not get it to start up again unless I charge the battery for a bit or hook it up to another car and even then its only that initial second of start up. Additionally, there are no longer any codes or check engine light, but there is a "pending p0335" on my neighbors reader. I thought maybe my crankshaft sensor was defective, so I got a second one and it is still the same deal.
It is also worth noting that I do not see any tachometer movement during start up. When we replaced the Crankshaft sensor the old one was destroyed. The wires on it were either burnt up or the plastic coating had decayed away almost completely; thus the reason it was shorting out.
My car has all new belts done through a dealership as of 10 months ago, so I doubt it is related to the timing belt. My neighbor thinks it may be bad fuel, although I always get good fuel and I also doubt this is the case. During key-on you can hear the fuel pump start up and other components all working normally, so it is unlikely related to that.

I have a 2003 2.4L 5 speed manual Santa Fe. I was parking my vehicle and removed my key as usual and realized that the car was still running. I put it into reverse rolled back and back into 1st to roll forward just to make sure I wasn't dreaming. I ended up pulling the fuel pump fuse and disconnecting the battery to turn it off.
When I replaced the fuse and reconnected the battery I was able to bump start the vehicle without the key in the car and drive it all the way home with no problem. I took apart all the plastic pieces around the Ignition and attempted to remove the cylinder but was unable to locate any sort of small button or pin to push on to remove it. Where is the release button?
What are my options here? Do I replace the cylinder first or get a new key, or is there something else that I should check first before I take it in.

It seems to have difficulty starting during stop and go like on deliveries. Also has problems after refueling. Is this caused by a faulty purge valve? If so where is it located?
