Crankshaft sensor wiring backwards???

[jdml98]

I have the California special Camry from 1996 and the distributor only uses 2 wires instead of four. The same crankshaft sensor is available from Oreilly's for both cars it is a CSS839 I believe. Any way the harness sensor wiring is 1 orange and 1 white. The new sensor wiring is 1 pink and 1 white and the pink hooks up to the white side of the plug. May be shooting in the dark because it ohms out but car still does not start. (See other thread)

Do they both have the same resistance reading?

N.E.O.

I don't know about each to ground but it passes the test of across each other with 1690 ohms. I just happened to notice this when I picked the car up from the shop this evening and was checking to make sure everything was reinstalled before I left with it. After leaving the deer stand (Hunting season in Arkansas) in the morning I will check this out. I just thought I would ask around while I'm stuck at work scratching my head about it for 10 hours.

You may have to check for signal for both the cam and crank sensor at the ECM.

N.E.O.

My thought is since there is resistance between them they must send a different signal. If they ohmed to 0 or O.L they would sente the same signal. I will check at ECM and if the signal is not within the variance I may swap them and try again. It may just be a generic wire color that Borg-Warner uses but it doesn't look right in a common sense point of view.

Ohmed to 0 or O.L., you lost me there!

Usually the wiring color for the pigtail harness doesn't matter very much, unless there is a polarity concern for the component. In this case, I don't believe there is.

N.E.O.

What was meant by that was zero or open line which is the same reading you get when you touch the probes of a multi-meter together while checking for ohms. That means no resistance and the wires would give the same signal to the recieving part. These have resistance meaning that each wire should give different signal to the reciever. Because this is a simple 2 wire hall effect sensor it may not make any difference.

0 Ohm means not resistance, and O.L. means open circuit, those are kind of two extreme.

Here are the specs for some of the parts for the ignition system:
Ignition coil:
Primary cold: 0.36 - 0.55 Ohm; hot: 0.45 - 0.65 Ohm;
Secondary cold: 9.0 - 15.4 k Ohm; hot 11.4 - 18.1 k Ohm;
Pickup coil: cold 135 - 220 Ohm; hot 175 - 255 Ohm;
Crank sensor: cold: 985 - 1600 Ohm; hot 1265 - 1890 Ohm.

Check each items cold resistance and see where you are at; might want to check some of them at the ECM too, just to be sure that it is the same or close to the same values.

BTW, don't worry about testing with the old distributor, I had my head crossed there.

N.E.O.

This being a hall effect sensor with just twowires it reall should not matter but the Toyota manual downloaded from Carystuff.com does show them as being a + and - input to the ECM for the NE circuit of the ignition system which is the secondary side that I don't have to make the spark.

Can you direct me to the manual you are looking at? As far as I know, all 96' 5sfe engine has a two wire distributor, no difference between Fed and Cal spec.

N.E.O.

The ignition and engine manual that this site links to in General Camry Discussion at Camrystuff.com. Only the EWDs with California show a 2 wire distributor the rest show a 4 wire or internal coil version????????
