This is the Mitchell Ondemand testing procedure for the cam position sensor ( test results indicated in red):
Quote:CAMSHAFT POSITION (CMP) SENSOR
1.DO NOT disconnect distributor connector. Using an analog voltmeter, connect positive voltmeter lead to CMP sensor signal circuit (Tan/Yellow wire on Cherokee; Gray/Black wire on Grand Cherokee) at distributor wiring harness connector. Connect negative voltmeter lead to ground circuit (Black/Light Blue wire) at distributor wiring harness connector. Set voltmeter to 15-volt DC scale.
2.With distributor cap removed, manually rotate crankshaft until pulse ring enters sync signal generator on CMP sensor. Distributor rotor should be at about 11 o'clock position. Turn ignition on. If voltage is about 5 volts, go to step 8). If voltage is not about 5 volts, check voltmeter leads for good connections. [glow=red,2,300]The voltage was at 5 volts here, so I skipped to step 8 as indicated. [/glow]
3.Repair connections as necessary and repeat step 2). If connections are okay and voltage is still not about 5 volts, check voltage at supply circuit (Violet/White wire on Cherokee; White/Black wire on Grand Cherokee) at CMP sensor harness connector. If voltage is present, replace CMP sensor. If voltage is not present, go to next step.
4.Backprobe PCM connector and measure voltage between terminal A17 (Violet/White wire on Cherokee; White/Black wire on Grand Cherokee) and ground. PCM is located on right side of engine compartment. If no voltage is present, see appropriate CMP sensor circuit tests in G - TESTS W/CODES - 4.0L 6-CYL article. If voltage is present, go to next step.
5.Check continuity of supply circuit (Violet/White wire on Cherokee; White/Black wire on Grand Cherokee) between distributor connector and PCM. If no continuity exists, repair wiring harness as necessary. If continuity exists, go to next step.
6.Check continuity of CMP sensor signal wire (Tan/Yellow wire on Cherokee; Gray/Black wire on Grand Cherokee) between distributor connector and terminal A18 at PCM connector. If no continuity exists, repair wiring harness as necessary. If continuity exists, go to next step.
7.Check continuity between ground and Black/Light Blue wire at distributor connector. If no continuity exists, repair wiring harness as necessary. If continuity exists, go to next step.
8.Observe voltmeter and crank engine. Voltmeter needle should fluctuate from 0-5 volts. If voltage is as specified, CMP sensor is operating properly and sync pulse signal is being generated. If voltage is not as specified, replace CMP sensor. [glow=red,2,300]The voltage switched between 0 and 5 volts as specified, so the CMP tested OK. [/glow]
As for the crankshaft position sensor, here's Mitchell's advice:
Quote:CRANKSHAFT POSITION (CKP) SENSOR Disconnect CKP sensor connector. CKP sensor is mounted in left side of transmission bellhousing. Measure resistance between terminals "B" and "C" at CKP sensor connector. See Fig. 1 (I would post the graphic that shows the pinouts but don't see how to add images to this post). Replace sensor if any resistance exists. [glow=red,2,300]My sensor shows no continuity, which I would think would be what Mitchell meant by not showing any resistance [/glow]

Mentor tips and tricks over the years from fabricating patch panels to removing pilot bearings and heads........ more hot rod tech but stuff i have run into over the years. I like post 158 part 1...................... Setting up DANA rears; 1. To determine your pinion preload shim, take a piece of thin electrical solder and put it behind the front outer race. Tighten the pinion until you get the right amount of preload, then disassemble. Mike the flattened solder, that's the shim you'll need. www.jalopyjournal.com/forum/showthread.php?t=435410&highlight=gas+weldingJustin Have anything to add that you were taught or learned from the old timers back when u were bustin knuckles for no reason? Slip the box end of a wrench over the open end of "working wrench" to add leverage if u cant fit or find that ratchet for the job!!!
