Question about 2007 Toyota Camry
Posted by Anonymous on
After the obvious, checking the oil level, the next step is to remove the oil pressure sensor and connect an oil pressure gauge. It sounds like you have already done this, so on to other things.
Try changing the oil filter in case it has a weak overpressure valve (meant to pass oil if the filter becomes blocked).
Some Camrys of this era suffered engine sludging, and if this has occurred it may have partly blocked the oil pickup in the sump.
After that suspect a faulty overpressure relief valve in the oil pump, or even a worn pump (this is rare in a 2007).
Worn big end and crank bearings will cause low oil pressure, but if that has occurred you would normally notice the engine burning oil (blue smoke). This and the oil pickup can be checked by dropping the sump, best done on a hoist.

The only positive way to check if the oil pump is working and therefore there is correct oil pressure is to temporary install a non-electrical oil pressure gauge that uses a small copper tubing to sample the oil/pressure and drive a needle on the gauge. Depending on temperature, idle should register about 20+psi. Having done this and confirmed that indeed there is sufficient oil pressure then it may simply be a defective oil sending unit. Otherwise, no or low oil pressure at idle is an indicator that the engine needs to be opened up again.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

Under the engine in the front you will see an aluminum cover.There is a square hole that fits a 3/8 ratchet remove this first.The new filter comes with a drain adapter that snaps in the hole under the cover.This lets the oil in the housing drain.Then take a oil filter cup wrench or a big channel lock to twist of the larger portion.Then change the filter and o-ring and reinstall.Make sure the o-ring on the square drive cover is there also

1993 Camrys take regular Dexron ATF. It should be changed every 30,000 miles. If you have never changed it, and it is over 100,000 miles, I would strongly suggest a professional "transmission-flush", with a designed specifically for flushing transmissions. To just drain the fluid at this point will leave roughly 3 quarts of dirty ATF in the system; a complete flush will eliminate ny dirty ATF traces.
