Kawasaki Fuel Injection Sensor Specs
Here's from my 1982 GPz1100 B2 factory shop manual:
Air temperature sensor spec(probably the one on the air filter housing, or next to it).
Meter at ohms X 1K ohms ( I use ohms X 2K as it works on my meter)
Disconnect the wiring from the harness, one meter probe to one of the connector pins, the other on the last pin.
Should read 2.0K ohms to 3.0 K ohms at 68 F, if your meter won't read this, try the 20K ohm setting.
A footnote says this reading is true when sensor temperature is 20C (68F), 4.7 K ohms to 7.6 K ohms when 0 C (32 F) and 1.4 K ohms to 2.2 K ohms when 30 C (86 F).
Engine temperature sensor spec:
Again, meter to 2K ohm settings, one meter lead to the push on terminal (remove the wire as it may give a false reading) and the other to a chassis ground(any Black with Yellow stripe wire is part of the ground circuit).
The readings will be the same as the air temperature sensor.
The TPS has an electrical connector, only the first three(3) contacts are used, counting from left to right as you face it.
From my factory shop manual I'm making it easier to get the readings, by using shortcuts).
1. Ignition switch off.
2. Remove the small SS clip holding the cable to the TPS.
3. Using a multimeter set on ohms, range of 2K.
4. Measure between the first electrical contact on the left and the third to the right.
5. It should read between 3.3K ohms to 6.8K ohms.
The next test will cover the range between idle and full throttle:
1. Set the meter's probes on the left contact and the one next to it, as this is the idle position check.
2. Readings should be between 2.1K ohms to 4.2 K ohms
Full throttle check:
1. Same electrical contacts used.
2. With the throttle wide open, readings should be between 0.35 K ohms to 0.71 K ohms, see if the resistance changes smoothly, with no fluctuations or wide variations as the throttle is closed down to the idle position.
3. If there are variations, try cleaning the TPS with the De-Oxit electrical contact cleaner/preservative. Open and close it with the throttle while spraying the cleaner up inside.
4.
