I know its not an oil change but it could be the bolt for the oil change is not there. If it is then the failure is inside, oil pump or oil filter clogged, an internal failure of some part in the oil system.
 
At any rate the Toyotal engine swap for that car would be the easiest way to get it back on the road. First I would find out if this engine has some bad history the 2002 Camry has a different engine design better design but gonna be harder to find at a salvage yard.
 
I swapped another Corolla engine into my 87 Corolla. I never took any parts off the "new" block, I just bolted the engine in and put on new water pump and the old manifolds. I didn't buy one gasket. The new engine had 79K miles compared to my old engine with 250K.
 
A good Toyota shop will keep the parts off your old engine to make sure it works with a new engine. This engine could be a re-manufactured block with cylinder head attached, and no valve cover, or simply one pulled out of a wrecked, or older Camry.
 
Your four cylinder is a 5S used in 1996-2001. Plenty of these in salvage yards. I paid $150 for my salvage engine. It was stripped of everything and only included the block, heads, valve cover, flywheel, and crankshaft pulley.

No spark on 2.2
 
Your coil should be on the fender well, it needs to have some volts on the small wires. Leave the key on for a few seconds and check the voltage there. The ignitor is under the coil, and it could be bad.They go bad if key is left on for 20 minutes or so.
 
Distributor has some circuits but I would have to check a wire diagram to see how it is wired.

#488 of 727 Camry A/C relay question by heisman98

Jun 23, 2009 (8:31 am)

I have a 1994 Camry and while I am driving the A/C light starts to blink and it stops blowing cold air. I have already had the freon and compressor checked. It blows very cold while it is working.
I have replaced the clutch relay under the hood on the drivers side but that has not fixed the problem. Is there another realy somewhere that I should be checking or change?
The only way I can get the A/C to work again is to pull over and turn the car off and on again.

Next time this happens and the light blinks, pull over without stopping the engine, and indicate whether the compressor clutch is engaged and the compressor is turning....or whether the compressor clutch is un-engaged and the compressor is not turning.
 
You should look at it beforehand, to understand the difference. Run the engine with the a/c turned off to see how it looks, and then have someone turn the a/c on so you see the clutch engage and the compressor turns.
 
Can you also indicate whether the a/c compressor cycles on and off by itself, when the engine is running at about 2K rpm.

When the light blinks the compressor definately disengages just like it would if you manually turned off the A/C. Any ideas on what it could be?

You didn't answer the question, as to whether the compressor cycles normally when running at 2K.
 
It should be cycling on and off.

Sorry about that. Yes, it does cycle itself on and off and runs just great when it is working. Sometimes it will work for 20 minutes before the light starts to blink and sometimes it last for 5 minutes before it blinks but it you can hear the compressor kick on and the rpms increase when I am just idleing.

Are the radiator fans turning on, and spinning?

Yes, both fans kick on and turn once the engine gets hot enough.

At this point, it will probably require some hands on to diagnose this.
 
Things we know/suspect at this point....
- Your system is cycling at 2K, which tells me that the compressor is able to pull down a vacuum low enough that it turns the compressor off (so low pressure switch is working, compressor is working, compressor relay is working), and it also tells me that the freon level is not overcharged. You also indicate it's cold when running, so freon level seems like it's not to much, and not too little, so that's goodness.
- The fans are turning on, so that tells me the temp switch appears to be working, the relays and fans themselves are working.
- You indicated that when idling and the compressor kicks in, the idle speed increases, so we know the idle up VSV is working and EFI main relay are working.
 
There's a couple things left which would be hard to figure out are working or not via the internet. There is a revolution detecting sensor on the compressor, which is used to verify that the compressor is turning and how fast it is turning (so it doesn't overspin). This sensor might be bad, or the wiring to the sensor is bad. There is also an A/C amplifier used for control, and the ECM computer.
 
The symptom that you mention that when you have this problem, you turn the engine off, and then back on and it works correctly, points me to an electronic control issue, which may be intermittent. Some error condition is getting set after a while of running, which turns on the error light and turns the system off. You turn off the vehicle, error condition is reset, and doesn't immediately return.
 
Other than the compressor sensor, I think you're going to need to get this to the dealer to trouble shoot further. Having a dependable failure is most helpful for the dealer to actually see the failing condition.
