So most likely, one of the sensors is sending the wrong or no signal. The electrical connections for the transmission are just tied off and not connected to anything. But most of them were from the transmission sensors, which makes sense since it does not have the original transmission on this engine. Retrieving this trouble code might lead you to believe it's time to replace the thermostat. A cracked magnet on the distributor that caused the module to read or not read cylinder firing position.
You can not put the wrong one in the wrong place, they will not fit. The only way to reduce the idle is to turn off the engine for a minute or so and then re-start it. Sep 19, 2011 coolant temperature sensor is located next to thermostat housing at front of engine in intake manifold you will see it right next to top radiator hose but this one reports to pcm the one for the gauge in dash or light is on the drivers side cylinder head you will see one little wire going to a sensor screwed in head near second plug back on drivers side Jun 19, 2010 The temperature sending unit is screwed into cylinder head. Just that the engine has driven for about 10 miles or so. The trouble code stands for coolant temperature below thermostat regulating temperature. Normally it is about 500 to 750 rpm.
I hope this helps you find the problem. It was right on target. It is an isolated ground from the chassis ground to eliminate noise for the temperature signal. The perfect example is when this part sets a code P0128 in memory. Are there other components that cause this? What other sensor could I check to see if it is the cause this high idle? If you have a scan tool, you may be able to view it. Careful, there is a sensor on the bottom and you'll h … ave to help it clear the hose under it.
If the senders resistance value corresponds to the correct temperature, then the problem would have to be in the wire or the cluster. The computer will also scale back engine performance settings if it detects that the engine temperature is too high, in order to protect the engine from possible damage due to. You can enjoy our Same Day Pickup option when ordering online. It is an isolated ground from the chassis ground to eliminate noise for the temperature signal. Check Engine Light comes on An is another symptom of a potential problem with the coolant temperature sensor. It was right on target.
Here's the point I wanted to make on this particular problem. It is a simple circuit, I don't see what else would influence it. Not saying it is not the gasket as there are a lot of bolts holding it down. Adjust the resistance dial to 1305 ohms and then to 49. Just out of curiosity, where are you taking your raw temp at? The only other thing I can think of is running a wire from the sender, to the cluster outside the harness and tapping it to pin 13.
I have checked with michanical gauge and temp. For this reason we recommend draining out the old coolant. . If solenoid has carbon deposits, wipe it clean. I turned it off and restarted it immediately and it still idled at 1,500 to 2,000 rpm.
I hope this helps you as much as it helped me Nov 28, 2010 I suspect your fast idle control is not working. This is done with the use of a scan tool using synch mode. Also check other sources of possible problems such as the brake vacuum booster and vacuum hoses on the intake. First, check to see if there is vacuum in the dipstick tube. Changing components immediately after they present the first sign of breakdown helps avoid expensive repairs and ensures worry-free and more comfortable rides for the life of your motor vehicle.
Follow the hose from the top of the radiator to find the thermostat housing. Obviously, you should never attempt this on a warm engine. I may have to borrow that scanner back to try it again now. Couple of interesting checks to make. On this chart, 89 ohms would put you at about 250 F, which is overheat. Then the process starts all over again. Rest assured that we stock customized sensors designed specifically for your make and model, such as a Dodge Ram coolant temp sensor and coolant temperature sensors for Ford Ranger pick-up trucks.
