Question about 1999 Toyota Camry

1 Answer

I have a 1999 camry (v6) and am trying to find out which pins on the diagnostic stick need to be bridged out to correctly set the engine timing. My previous 1994 camry (4cyl) had the following bridged te1and e1.

    I am actually trying to check, rather than to adjust the timing at present. My reason for this is that the car seems to be heavy on fuel, takes a while to start and has an occasional pinging under the bonnet. The diagnostics stick on our new camry is similar to the old (4cyl- wide bodied), with the pin configuration in different spots. for example- E1 on the v6 engine exists, but TE1 has no wiring to it. The only other connection in that group of nine pins ia position b. Are you 100% sure that bridging is not possible on this vehicle?. From what I am able to see, if bridging is used, it would appear that for this model of car that E1 and b may be the likely combination?. I thankyou and would appreciate your further thoughts.

There is no bridging on these vehicles. Those features were only available on OBD1 models prior-1995. May I ask why you are trying to adjust timing??Timing components in these engines are computer controlled!!

    I am actually trying to check rather than to adjust the timing on this vehicle. The reason for this is because the vehicle seems to hesitate at start up, the vehicle intermittantly pings and also, the vehicles fuel consumption seems to be a little eccessive. So, if you are saying that there is no bridging in the diagnosis port, then how is it possible to make the efi system run in a way to accurately check and or set the vehicles timing?. Thankyou for your previous response and thoughts.

    There are no SELF-Diagnostic system in this vehicle!!!. Toyota uses that same connector for their very own diagnostic system for years til present (they're all wired differently). 1995 (4cyl-5sfe eng)/1993 (v6-3vzfe) was the last year they used OBD1 self-diagnosis, OBD2 regulation was federally implimented starting1996!!OBD2 does'nt support self diagnosis, and must be read by an OBD2 reader. The reason for the v6 starting an earlier year is due to a re-designed V-6 (1MZ-FE eng) engine that started production in 1994. If you dont believe me call your dealer, and please dont vote 50% when my answer is 100% correct.

Hi R,
If I understand correctly the sound you're describing could be something known as 'pinking' It occurs when the ignition timing is too far advanced and can damage the engine. Make sure that you're using the correct octane rated fuel in your vehicle and thereafter take it for a tune. Whoever does it, should set the timing at 10 degrees BTDC. To set the timing correctly, open the diagnostic socket in the engine compartment which when standing facing the front of the car will be on your right and the vehicles left. Open up the cover and bridge between T and E1 (A small directory is inside the same cover, which will help you find the correct connections) Only when the bridge is connected can the ignition timing be set correctly. This should be carried out with a strobe timing light with the engine running.

Can u help me with a timing setting on my 97 toyota camary le 2.2ll or some kind of mark to guide me on?


Hi,
Are you looking for ignition timing or valve timing marks?
The ignition timing is set at 10 degrees BTC. the marks are at the front of the engine and the degrees are scaled onto a raised molding on the plastic timing belt cover. There is a line marked on the pulley. Paint with correcting fluid the 10 degree mark and the pulley mark. Correct timing is 10 degrees BTC.
Before setting, open the diagnostic connector in the engine compartment and using a short piece of electrical wire and bridge between "T" and 'E' If this is not done the timing will not be corrected.
If you've replaced the timing belt and you're looking for the timing marks, the mark for the crank shaft is a raised casting forming a small pointer for the crank shaft which aligns with a groove in the crank timing gear....When looking from above at the relevant section of the engine, it will appear on your right hand side just above the crankshaft timing gear.
The marks for the cams are holes drilled through each and these should be aligned with punch marks on the cylinder head. The best way of doing this job is by using a mirror and illuminating between the cam gears and the cylinder head.
Hope this helps
Regards Johngee10

1999 Toyota Camry V6 idles rough and stalls after starting. No check engine lights and runs fine otherwise. Has only happened three times in the last two months. After keeping the idle up and running car...


yes it could be a fuel related problem, when was your last tune up, it could also be a spark issue, old or corroted spark plugs will sometimes not put out the correct amount of heat to ignite the gas correctly till it runs for a while, if the check engine light isnt lit, it will almost have to be something simular to this

Check engine light just came on 1993 toy camry


First you need to find out what the fault code is that is making the check engine light come on. To do this, locate the diagnostic connector under the hood. It will be a black rectangular connector approx 50mm X 25mm with Diagnostic written on the cover. Open the cover and on the inside of the cover will be a diagram of the connections and their different labels. Locate pins labelled TE1 and E1. Switch on the ignition switch without starting the engine and with a small jumper wire bridge between pin TE1 and pin E1. Observe the check engine light on the dash and you will notice that it will be flashing. Read the diagnosis code as indicated by the number of flashes that this light makes. Each code will be displayed by first blinking the first digit of the code, then a pause and blink the second digit of the code. For example, Code 52 (knock sensor signal) will flash 5 times, pause and then flash 2 times, then a longer pause before it goes onto the next fault code if there is another one. Once it has gone through all the stored fault codes it will go through the sequence again starting at the first fault code again. Due to the many different fault codes that can be obtained it would be better to post another question for the fault code obtained. Good luck!

1993 Toyota Camry V6 Timing Settings


Get a T belt from toyota. It has 3 white lines on it and and arrow mark. 2 lines are solid and one is broken. Put the arrow facing away from the engine. The cam gears have a dot punched into them near a certain tooth. This is where the solid white lines will line up with. The crank gear will have a dot also. It will line up at 90 degrees from the top, towards the front of the car. This is where the broken line will match up with. With the belt installed with all lines on their proper dots and arrow away from the engine, you valve timming is correct.
Of course you need to remove and compress the tensioner also. I assume you know this already since you didn't ask.

There is usually a diagnostic box when u raise the bonnet. It is located at the passenger side, close to the body of the vehicle. If u open it, u will notice that there r 2 points E1 & TE1. Bridge those two and observe how the engine light flashes, ie how often after pauses. The blink between pauses represents a digit. Remember it and tell me what number u ended up with
