Ignition switch connector

Good morning again.

Solder and shrink wrap is the best way to ensure a good connection.

Are you replacing the pigtail or just one wire?

Roy

I am replacing the wire and the connector and pins.

Check and see if you can get a pigtail. That is a new connector and wires. All you have to do is solder and shrink wrap to the existing harness.

Roy

Yes, it is what I have. Thanks

Good deal. Make sure you shrink wrap the joint after you solder it. Butt connectors will not work. They will overheat from the current draw cause a voltage drop.

Once you are finished. Then drive it and see if any codes return.

Roy

Okay, I will do.

Oh, I forgot to tell you the PCM was replaced two years ago. The p0882 always triggers when starting this engine.aka vehicle speed 0 mph. Also, I replaced filter and transmission oil two weeks ago. However, the codes were there before transmission fluid replacement.

Okay, let's cross that bridge after you replace the connector. You may have a voltage supply issue that is causing those codes.

Roy

I replaced the connector solder the wires and heat shrink them. P0218 came back I think not sure, only when the AC is on. when I turn the AC on I checked the coolant temperature with code reader it was 221 and kept climbing. I did not hear the high speed fan turns on. Only heard the fan running one speed.

If you turn on the AC does the high speed work on the cooling fan?

Did you replace the thermostat?

Roy

Yes, the fan turns on but does not seem it is high speed. I just jumped the fan pig tail. I jumped the middle pin ground with the right pin fan turned on. After jumped ground with left pin fan turned on, however they seems they are same speed.

Check the dark blue/orange wire for power. that is the high speed motor control. It comes for the TIPM. If it has power, then the fan motor is bad. If it does not then the TIPM is bad.

Roy

There are two relay on top of fan. When AC on both relays are closed. I guess the high speed in this car and fan is running I did not check yet at the fan harness if there are power in both wires.

Check the powers per the diagram I sent you and let me know.
Roy

The car fan is 3 pins and the diagram has 4. Also, in the diagram is not showing relays which I have in car.

Are the colors right at the fan? The ground is the way it is mounted.

Is this a turbo or non turbo?

Roy

Non turbo. I cannot see the colors there are some burn marks.

Check the connector on the fan for any damaged or burned wires. Test the wire I told you for power.

Roy

There is burnt wire harness side not fan side they are thick wires.

Can you post a picture?

Did you check the voltage?

Roy

Inside the connector is black aka burnt. I did not check voltage I think needs to be replaced, spliced or something else.

I measured the temperature of the transmission with infra red thermometer. Today outside temperature is 100 F.
Oil pan temperature 157.
Transmission casing temperature by the engine block 212.
Oil cooler temperature 180.

Can you post a picture of the connector?

I need to jack the car up. My other significant took the car when I have chance I will sir. Are the temperatures good?

Here is the pictures.

Here is the pictures. The tab inside that hold the pin is broken. I went to the junk yard and replaced the harness. It has two relays and two connectors.

Those connectors are no good. They are burned up from high resistance.

Is that the original or the replacements?

Transmission fluid temperature is a bit high. Wondering if the cooler may be restricted.

Roy

That was the old one. The new one aka junk yard ones are good and shiny. Yes, the code came back today. It is hot day too as yesterday 98F. How to check the transmission oil cooler?

Is the cooler external or inside the radiator?

what code returned?

Roy

It is external mounted in front bottom of radiator.

It would need to be flow tested by someone to be sure there is no restriction. It would be cheaper to replace it than have it checked.

Take the temperature at the top and bottom and see what the temperature difference is between the two test areas.

Roy

At the top where the rubber hose meets the cooler the temperature is 136 at the bottom where the rubber hose meets the cooler temperature 110. Today's temperature 72.
The code that returned is p0218.

The temperatures are not enough change. I would start by replacing the transmission cooler.

Roy

When I wiggled the PCM connectors p0882 came back and car went to limp in mode.

Okay, remove the connectors and clean them. Make sure there are no dirty or damaged pins. Use electrolytic grease on the pins for a better connection and retets.

Roy

Forgot to tell you, when the car went to limp mode security light was flashing airbag light on and all gears were selected on dashboard. After I pushed in connector the car is good the only code left is po218. I will do what you told me.

Okay, clean the connection and see what happens.

Roy

Hi,

Can you please tell me where the transmission temperature sensor is located?

Removal:

The valve body assembly must be removed to gain access to and replace the transmission range sensor.
1. Disconnect the battery cables.

17. Slide Transmission Range Sensor (1) up the manual shaft and remove.

How did the transmission cooler get clogged up? I have seen a video showing someone was cleaning cooler using a machine and in the filter was like metallic particles.
