I have a 2000 ford focus 1.6i zetec can you tell me where the coolant temperature sensor is located please


The temp sensor will be close to or in the thermostat housing.(top radiator hose). A temp sensor also controls cooling fan. this sensor is usually mounted in the radiator. I strongly recommend that you purchase a Chilton manual for this vehicle.

I have whirlpool 650s top loader washing machine.it shows PE error when switched on.so please tell me what to do to get rid of this error message in the board


the PE error relates to the fill level of the washing machine. The fill level sensor is a pressure operated device. There is a sealed air line that goes from the bottom of the tub to an air pressure sensor. As the tub fills, it compresses the air in this air pressure sensor. When the tub is filled to the level selected on the dial, the sensor stops the fill cycle.

This air line can be plugged or the sensor itself can be faulty. This air pressure sensor is usually located near the top of the tub just under the top cover. If you can locate it, disconnect the air line from the pressure sensor and blow through it - it may be blocked by lint and soap from several washing cycles. There may be a filter in this line to help prevent this blockage. But the filter may have become blocked itself.

Harley speed sensor


Hi Mikael, always check your instrument fuse before performing the next procedure, try cleaning your speed sensor located on top of the transmissions right side between the top cover and the chrome starter end cap on Twin Cams and on top of the engine case between the rear cylinder and the starter motor for Sportsters. Remove the the bolt that secures the sensor and pull it out of the transmission. Inspect sensor for obvious damage and repace if necessary. If sensor has no damage then wipe clean any obvious contamination like micro fiberous material with a clean rag and reinstall, torque bolt to 8 ft lbs.

How do you install a fuel tank pressure sensor on a 1998 Saturn SC2? I understand that it is on top of the fuel tank, but that does not tell me how explain how to replace it. Please help!!


You will have to drop the fuel tank down far enough to access the top of the fuel tank. You will probably have to remove the exhaust system and all hoses and electrical connections. Disconnect the connector from the sensor, pry it out of the top of the fuel pump module. Be careful not to break the top of the fuel pump module. When installing the n

Document feeder door open


The doc feeder is the one on top, there's a sensor in the hinge at the rear. If the tab is broken from the top cover, you need to fold a piece of paper and put it inside the horse shoe shaped sensor to get past the error.

Error message tells me the top is open it isn't,


when the top is opened there is a sensor which comes up and the cartridges come in the center.when the top is closed the sensor gets pressed due to the closed topo and the cartridges move towards in.as the cartridges are coming in between and you say top is closed this indicates that the top lift door sensor is out of position or it is not getting pressed just check out properly the sensor is getting blocked or its broken.
