Lexus GX 2004-09 :: P0016, P0018 Diagnosed - Timing Belt Put In Backwards
Jul 13, 2011
My mechanic (also my Brother - certified dodge mechanic) says he might have put timing belt in backwards (as in the side that is supposed to be facing left, is facing right and vice versa). I dont want him to have to do the whole job over again unnecessarily.
I do have the codes P0016, P0018 (Camshaft position sensor and crankshaft position sensor correlation) and of course a check engine light. Otherwise the vehicle is running great, no timing issues that I can notice.
This is a 2006 GX470 4.7L V8 2UZ-FE engine.

After timing belt change code P0016 with Check engine light trac off and VSC light on.
Put on the entire kit...timing belt,tensioner, idler, and water pump. When I took it apart to put the new cam crank sensor I inspected everything and all looked good.
Changed the sensor and reset code, a few hours later back on. Car seems to run fine. I didn't think the sensor was bad. Car was running great...just due for timing belt.

I have been driving my car with a known P0016 and P0018 codes for quite a while. I know, I know.... Car was not worth sinking a lot of money into so we decided to run it till it died. It has run great for about a year but now it finally has problems. Day before it ran great. First thing in the morning it tried to start and then stalled. It will try and start and putt, putt two or three times and die. I think it has jumped timing. Before I trash it I would like to make sure that is the problem. My question is, can I check for a jumped timing chain at home without doing a major disassembly? I don't have access to a VAGCOM. If that is what happened I will get rid of it and move on but I would like to verify that is really what happened. There is no valve clatter so I don't think it jumped enough to damage the heads.

I just changed the timing belt on my sisters car and finished yesterday and drove it today. A check engine light came on so I went to check it out and P0016 popped up. I've done some research and people say that it might be that the timing belt is misaligned or loose. I tightened the belt not too tight but not too loose. Note: I also spilled coolant on the crankshaft pulley and a bit on the belt itself. The car idles rough when driving too. I will tomorrow take off the cover and check the tension of the belt.

Replaced my Crankshaft position sensor and cleared my codes but I'm still getting a P0016 and P0018 error. Car runs fine at the moment. Can't smog and therefore register it till I figure it out. Next step is replacing the Camshaft position sensor.

Had the stem seals replaced on my 2004 toyota camry 4 cylinder (2az-fe engine). The job went quickly and the realigned both camshaft marks to the respective yellow link and #1 and #2 bearing marks per the manual. However, now getting a P0016 error indicating timing is a bit off. It is difficult to verify that the top camshafts are aligned correctly to the crankshaft without taking off the side cover. Doing that is a 6 hour job and requires an engine lift.
Is there any easier, surefire way to check and adjust the timing on this engine without having to take off the side cover? It is probably just a tooth off since it is running well.
The attached pictures show how it was aligned before buttoning up.

I was wondering if the timing belt on my 05 RX 330 needed to be changed due to age and not miles. The car only has 72k miles on it but it is 10 years old.

I have a GX470 and just had the timing belt replaced. Now my "airbag light" stays on all the time.

I was driving my 2005 RX 330 (138k miles) North on I-75 through Atlanta in rush hour traffic when the car completely died in the left hand lane w/ no shoulder. GDOT stopped six lanes of traffic to push us up and over a couple of hundred yards to a right shoulder. It was determined that due to a coolant leak from the water pump the timing belt malfunctioned and shredded.
I had heard that the water pump should be replaced during the 90k maintenance when the timing belt is changed, but my water pump was not replaced according to my maintenance records. I understand from reading a couple of posts that this isn't always required but that they do check the water pump. Is this correct? And if so should they have noticed that there was a potential problem?

So about six months ago I bought a used 2010 mkvi gti from a small dealer. Now here's my problem. The other day i started my car and it was a rough start. And the car ran rough. I stalled twice trying to back up. Then the car threw a light. I didnt drive it at all. Shut it off and left it. Read the code that night. P0016
Now I know the timing tensioner thing has been beaten to death. So that's my first thought. However, there was never a rattle or a noise. Nothing like that. Is it possible? All four cylinders have compression. About 210psi. I don't know if that is good or bad. Plugs are worn but look good enough. Not too much junk on them. Coil packs look "newer" and they are the "upgraded" versions. Other than the tensioner what else could cause a p0016 failt?

I was thinking about checking out the above vehicle at my local dealer (Chevrolet). They're asking 15.9k and it has 57k miles. I need to know if it has a timing belt or a timing chain and how reliable is the engine/transmission.

I was told by VW service that my timing belt is loose and needs to be changed. Is it possible to know that without taking things apart? The belt was changed at 80k miles. The vehicle is at 132k miles now. Its a 2004 v8. the quote is $1400 which I suppose is in line with what these cost but I'm wondering if I can wait until 160K before changing it.

I purchased a 2004 volvo c-70 with 35K miles.The manual says to replace the timing belt at 100k or 10 years.With such low miles do I need to replace it in 2014?

1. When I am on a hill facing up a few times when I put my foot off the brake my car starts rolling backwards like it's in neutral. Then when I put my foot on the gas there is a funny noise and it seems the gear or something happens and I get power to move forward up the hill. The noise to me is quite unnerving like it should not be happening.
2. A couple of times when I have backed up out of a parking spot, when I come to a stop I hear a noise like a spring and while I am turning the steering wheel and putting the car into drive.

Recently I changed the timing belt on a 2004 Passat 1.8T and I realized I put the timing tensioner off by a few millimeters due to misunderstanding. I started the engine and it didn't sound very healthy. So I took off the timing belt and realized the tensioner was off by 8 millimeters. I corrected it and restarted the engine and it began back-firing. I re-checked and replaced the belt 3 more times and it still back-fired. The engine runs perfectly from a few seconds to a few minutes, then begins back firing and it stalls out. I had a recent post and I had suggestions to check all hoses, connections, etc. and to scan the computer for error codes. I did so and got the codes P0300, P0302, P0303, P0304. These codes mean back-fire in cylinders 2-4. I don't see any valve adjustments in the engine so could the valves be bent and do I have to replace them? God forbid D: Or do I have to reset some kind of computer code in the car or any other error that may need adjusting? All connections, hoses, wires, etc. are good. I've been a professional mechanic/technician for 25 years now and fixed cranes, bulldozers, semi-trucks, and anything else you can name that has wheels and is land based, all sorts of engines, gas, diesel, ethanol, you name it... I also worked on several VW's, including my own, and figured this V-Dub would be a walk in the park , but it turns out this Passat is the most complicated thing I've worked on in my life!

I have 2004 Chrysler Sebring base model 4 cylinder with 90,000 miles. Paid off long ago. The schedule says its time to change the timing belt but no symptoms. No other issues and have kept up the maintenance. The cost is around $1000. I need the car to last 2 more years until our new car is paid off. Should I do the repair or play the odds that it won't break down?

The timing belt on my 2004 Chevy Aveo broke last week. I have it at a mechanic who got a new timing belt on to check the compression of the engine. Bad news: no compression. So far they haven't taken the head off to inspect the inside. This includes timing belt/water pump, cylinder head gasket removal and replacement, cylinder head check, some misc labor, lube, oil, and filter...
However, another mechanic is suggesting that I replace the engine instead with a used or refurbished engine with less miles. He says that it doesn't make much sense to put new parts on the top end of the engine. The engine itself has about 153k miles on it.

I just had the timing belt (water pump and thermostat) replaced in my 2004 V8. I drove it home from the dealer (75 miles or so) without incident. Drove it to and from work (4 miles) without incident for a few days.
Last night I drove ~5 miles, idled in a parking lot for ~10 min and then drove another 5 miles and it overheated. Once I shut off the car it would not come back on. I waited for it to drop below 200C and it still didn't start. Electric consumers would come on all was well....but no start.
Car was towed to the local VW dealer who do not have a phaeton tech. After the hour and half it took for the tow truck to arrive and half an hour to tow it....it started up.
I am now thinking about my next move. As I read through everyone's overheating experiences they are mostly
1. Failed thermostat (which one? does the bottom thermostat control water pump operation?)
2. Fan issues
3. Air in the coolant line following a flush (could be, but I drove it home in the cold on the first day with the heater on)
4. False readings due to a bum (upper?) thermostat.
I have a VCDS but have not been able to get out to the car to give it a shot.

Does the 2014 es300h have a timing belt that requires changing at specific intervals? The dealer told me he thought they are using a timing chain hence no scheduled maintenance.

Serpentine belt on a 2006 Honda Odyssey fraying and then ripping into the timing belt causing that belt to break? I recently had this scenario given to me as the cause of my recently replaced timing belt breaking.
