Ask Your Own Toyota Question
Customer reply replied 1 year ago
they go to a kind off black sensor in the top of the compressor and it is secure with snap ring ?
Toyota Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 1 year ago

yes ,so that compressor has 2 plugs one for compressor itself & the second one is for the front magnetic clutch of the compressor pump that engages when commanded on so your compressor starts pumping

Hello. Different expert here. Please allow me to add some input on your request. There are two sets of wires that connect to the compressor. One is power for the compressor unit, and the other is the RPM sensor. If any of these wires have incurred any damage, and are not properly repaired, the AC compressor will not engage. Most likely, the RPM sensor wires are damaged, or, the RPM sensor itself is damaged. The RPM sensor is in place to send the RPM data of the compressor to the AC amplifier assembly. As long as the RPM data is within the specs, the AC amplifier energizes the AC compressor clutch. If the RMP signal is lost (like an internal failure of the compressor), the AC amplifier shuts off power to the compressor (to prevent the drive belt from smoking when it tries to turn a seized compressor). The RPM sensor needs an oscilloscope to diagnose its output; a scan tool cannot read the RPM sensor. This would require further diagnosis in order to determine the exact cause with an oscilloscope; there is no easy way to determine proper RPM sensor diagnosis without the scope. If you have any questions, please feel free to reply to me. Thanks.

Thanks for your replay ,where the location for RPM sensor and how many wires should goes to the RPM sensor and what's the Color code ?
Customer reply replied 1 year ago
The only problem I do have with AC compressor is after the accident there is a sensor in the top of the compressor I believe they call it the magnet compressor sensor , The original plug crashed after the accident and all the wires are exposed there's a three wires Blue, yellow ,green I don't know which one goes left which one goes right and which one in the center of the plug?
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

You are describing the RPM sensor. There are two separate items on this compressor. One is the clutch, activated by commands from the AC amplifier. The other is the RPM sensor. If the wires are crushed, due to the severity of the impact, it is very likely that the sensor is damaged.

Ask Your Own Toyota Question
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

The sensor is, for all intents and purposes, a magnet. As the compressor internal shaft spins, the magnet counts the RPM of the shaft. A frontal impact that smashes the wire harness almost always destroys the sensor. The clearance between the magnet and the shaft is very precise. A frontal impact can and will cause this clearance to change.

The Blue wire on the compressor is power to the compressor clutch. It connects to the engine harness wire connector where that feed wire is blue also. The Green wire is connected to the engine harness purple wire at the wire connector. The Pink wire at the compressor connects to the light blue wire at the connector.

I do have new sensor ,but the original plug harness for the car smashed and I need the color code that go the sensor ,if there is any way to provid a picture for the plug that will solve the problem ?
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

I gave you the wires for the RPM sensor above. From the sensor, one wire (Green) connects to the Engine harness Purple wire. The Sensor's pink wire connects to the light blue wire on the engine harness. (assuming, of course, that the engine harness has not been modified or altered).

Customer reply replied 1 year ago
Please see if we was in the same page ,is this the sensor you was talked about ?
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

Is that wire connector a 1 wire or a 2 wire connector?

Ask Your Own Toyota Question
Customer reply replied 1 year ago
It's 3 wire connector Blue ,green,yellow ,the connector plug(car harness) missing due to the accident ,I do have after market plug that fit for it but has a White wire ,I need to know the color sequence in order to put the wire together
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

Looking at the back of the connector (the wire harness side). with the lock tap in the 12 o'clock position, the terminals are 1,2 & 3, left to right.

Terminal 1: RPM SENSOR (green)

Terminal 2: RPM SENSOR (pink)

Terminal 3: Magnet Clutch (blue)

But there is no pink color it is yellow ?

The RPM wire could be yellow; however, my diagram clearly shows pink.

Customer reply replied 1 year ago
Can see the diagram ,and what that sensor called cause I got many names for it so far ?
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

This would show continuity measured from the yellow wire at the compressor to the 20 pin grey connector behind the glove box , pin 7

Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

yes

Ask Your Own Toyota Question
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

The RPM sensor Pink wire (yellow in your case) should be connected to pin 7 of the grey 20 pin connector.

Hi there
So I did some test unfortunately the wires DID NOT Mach the wiring digram u mention above ,I have green wire conceited to PIN number 7 and yellow wire connected to PIN number 30 ,I find the wire digram that Mach my vehicle , and the wire plug connecter to the AC compressor is BLUE ,GREEN,YELLOW ,the only problem I have is to know the wire position for the BLUE AND YELLOW wich one in the left and right for the car harness side AC plug connector
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

Please upload a picture of your wires, and their connection area. That would be a great help.

Ok. are there any remnants of the old connector? if it is a 12 pin connector, the pins are: Yellow: 3 Green: 4 Blue: 5

If it is a 3 pin connector, the pins are Yellow: 1 Green: 3 Blue: 2

Ask Your Own Toyota Question
Customer reply replied 1 year ago
It is 3 pin connector but the yellow wire number 1 wich Side of the connector left or right ,this is my problem the yellow wire and the blue wire position
Note: I market the green pin with 7 and yellow with 30 cause that is where they are at the AC amplifier ecu connector
Toyota Mechanic: Toyota Service, Toyota Expert replied 1 year ago

The Bkue wiure goes to a junction connector where it splices into several other wires. The feed for that junction connector is via a light blue wire from the AC amplifier, pin 13
