REPLACING 2003 HYUNDAI SANTA FE AIR COMPRESSOR 3.5 CODE
Unlike a lot of the OBDII codes, this code has to do directly with engine combustion. These particular codes indicate that there is a misfire in one of the other cylinder’s as well.įixing P0303 should be considered a high priority. It will often be accompanied by codes P0301, P0302, etc…. The nice thing about P0303 is that it’s a cylinder specific trouble code, which makes diagnosing the problems simpler than P0300, which means that the cylinders are randomly misfiring. P0303 should not be ignored, and can be a threat to the drivability the Hyundai Santa Fe. They are kind of expensive as well.P0303 is a relatively common Hyundai Santa Fe trouble code. If the plugs aren't misfiring don't mess with them! A better question is what is up with the individual ignition coil packs, one would think having a dedicated coil-per-cylinder would increase reliability but that doesn't always seem to be the case. The guys who run fleet maintenance don't mess with plugs either.

The automotive forums are chock full of "I changed the plugs out at 50,000 miles, and now it has a miss" etc. If there are no codes generated, fuel mileage is in line with where it should be, you couldn't pay me to mess with them. A further complication is they can tend to break off in the cylinder head during removal attempts. While a misfiring plug may not be noticable to the driver, emissions and pollution will increase, fuel mileage start to decline.Īnyway that's all gone now, factory fine wire platinum plugs are good for several hundred thousand miles these days. As the old style conventional plugs wore the electrode and ground strap would erode, increasing the voltage required to jump the gap. It's a fricking nightmare on certain makes and models.Ī good hot ignition spark at the plug is enhanced by sharp, square edges. While I consider myself to be a longstanding longtime lifetime member of the OCD mechanic club, it should be pointed out spark plugs are no longer a routine tuneup item anymore! Honest Injun! You guys are likely wasting not only your time & money, but are also increasing the likelihood that something unrelated yet (important and $$$) in the way is damaged, reassembled incorrectly, FOD, etc., etc.Īt one time changing a set of spark plugs was a necessary and even relaxing ritual, a Sunday morning affair accompanied by a cold beer and friends, the radio, a grandson or two "helping" etc. Need capacitors, resistors and other parts-> The new alternator wouldn't fit the brackets, my angle grinder took care of that. I need to replace the front rotors and brakes, and I have the parts but I was too tired at 2am this morning, I'll do it another time. I texted my friend who owns a repair shop and told him he is worth every penny he charges his customers. While I was under the car I changed my oil which was overdue. The good thing was I found out why my A/C wasn't working for the last 2 years, a wire was broken going to the clutch so I fixed that. Every bolt was tightened by a gorilla it was amazing I did not snap a bolt with my 2 foot breaker bar. Mind you, there is so little clearance to do most of the steps thank god I have a good set of tools otherwise I would not be able to do this. I had to remove the tire, remove the under carriage cover, fender splash guard, serpentine belt, tensioner and idler pulleys, air conditioner compressor, unbolt the power steering line from the chassis, remove the air conditioner bracket, unbolt a couple of other brackets holding the power steering hoses and other lines, unbolt a bracket in front of the alternator, disconnect the electric connectors to the alternator, unbolt the alternator, remove the alternator after using a hammer because it was stuck on the bracket, and do the reverse to put the car back together. What were the engineers thinking? Basically you work through the fender well and the bottom of the car.
Well, the replacement took me about 13 or 14 hour over 2 days. I decided to replace it my self as how hard can it be. My alternator died on my 2003 Hyundai Santa Fe with a 3.5 liter V6.
