AKA:  CPS, CAS , CMP  (crank sender is CKP 1996 1.6L)


To test the sender you can use a simple volt meter (an  O-Scope or GMM or DSO is best) on the output of the sender , in circuit , key ON, in all cases 1991 to present.
Except the CPS1 in drawing #1 below.  This sensor is unbuffered and must be scoped to see it.
Attach meter or scope ( as appropriate) to the lines marked SIG. (float the scope so as to , not cause ground loops)
The buffered hall sensors will produces a perfect square wave and will be consistent.
The unbuffered coils  CPS1 (for example)  will be more Sine wave like.  And weak.
The buffered and even the 8v CMP produces a perfect 5vdc square wave as seen here.
The use a voltmeter , attached will produce 5vdc then 0vdc then 5vdc as the motor is cranked over slowly.
Heat the sender with a heat gun or cool it will cool spray (in a can) to make the Photo2 Sender fail , it is common to fail at heat soak.
Buffered VR senders do exist and I'm not sure if Suzuki uses them. But here is one.

This web page is one of the best I have seen on the HALL compared  to the VR sender, topic. ( with wave forms)

Really, what is in side is not near as important as , is the signal analog or is it digital? , and if digital is it 12v or 5v signal. ?
With this data you have an idea of what you expect to see.

Photo2:
   1.8L DOHC 16V Sport Sidekick Cam sender. CMP2,  4 pins.  (weak technology)


Drawing 1: 
1996-98 Suzuki sports and similar on all future Sidekicks. All motors. This one is unique in the fact of 2 types of senders were used.
This is the first Sidekick years that like to fail CMP's , they will heat soak and car will not start. (check DTC's (pendings too)  or check for spark loss)
There are 2 sendors,  one shows TDC the other tells ECU what cylinder is firing (Distributor less ignition Sysetm (DIS) needs that information to run)

Other facts:
The early 8v TBI cars, the  CMP sensors are VR senders and must be gap tuned and are hard to test , see FSM for details , Samurai's have these.

The 89/90 Kicks have fully integrated stand alone distributors and make there own spark and advance. The tests for this are unique and the FSM covers it. (if spark is lost the whole inside electronics modules x2 of Distributor must be replaced.)
These 2 years need sensor gap setting too.

The 91 one began the first ECU spark generation system seen in Photo 1.  No gaps setting , and 100% never fail reliable , 91 to 95, 8v and 16v are all like that , they never fail.

The 96 1.6L then move the ignition coil  and igniter into the distributor and makes testing the this more difficult.(see drawing4)  but again, they never fail.
