Thank you, my coolant temp gauge did not read at all I done the ohm's test you described and had no resistance I swapped the sender unit for another second hand one I had on another engine, it had ohm's reading's on all 4 pins now temperature gauge is working and funny enough my oil pressure gauge started working this didn't work before I changed the coolant sensor, so thank's again.
Great video, but confused on how to test a 4pin sensor? Does this mean you test them diagonally? +mm to one pin and - mm to the other pin? Cris cross? Would you please comment, how to test? Thank you, in advance!! Gracias!!! 👍🙏
hello, my 1986MB300E has the 2-pin coolant temperature sensor like the one you show on the video. Car runs fine but I checked to see the resistance on both pins and the potentiometer doesn't show any value with cold or hot engine. I assumed the sensor is bad and ordered a new one. Do I just unplug and screw the new one? Also to test before installing the new one, what resistance should I get in a hot glass of water and a cold one please? Thanks
Hello. Concerning the values - here, I will send you the link to my instagram page where you can read the values. If you don't get any values both on the potentiometer then check the wires if you have continuity. The link for the CTS instagram.com/p/CTLYUPdKBQ_/
Please help, So im having issue with my cold start valve, and with my multimeter, i check the two pins on the coolant temp sensor, and my mutlimeter start beeping.. is that mean that i have bad sensor, or there is short in side the sensor?
Usually the values you have to get are 2.5kohms when the engine is cold and 350ohms when it's at 80 degrees C. Do the check like me in the video. If this is not the case then it's either the sensor or the wiring.
Hi Suffering rough idle for months. Checked my engine temperature sensor today. When the enigine is cold it gives a reading of 2.5,kohms. When the engine is hot the sensor shows .5 kohms. Could this my issue ?????? Keep up the great work. Very informative vids. Cheers
You have a bad value when the car is warm. Both pins must show the same value. When warm you should get 350ohm. Also tell me about your car - I need the engine code as well as the year of manufacture. Provide me also with the things you have done on the car, replaced.
@@mercedeske Hi. I have a 1989 260E. M103 Engine (No O2 Sensor) Engine Code - 10394022065054 I have a rough Idle with an occasional stall for the past 2 years that I’m desperately trying to figure out. The revs on warm idle are at 500 RPM. It has a slight shake. I cannot identify if its an Ignition, Fuel or Vac Problem. Ignition Checked all individual components and all appear to be working fine. Spark appears to be strong on all cylinders. I changed the plugs (Denso Q16TT) and distributor cap (but not the Rotor). Also replaced OVP. Fuel I‘ve changed the Fuel Filter and Fuel Pump Relay. Checked Accumulator. I’ve done several tests in terms of fuel pressure and flow. Fuel flow produces 2 litres of fuel per minute which is a good indication of strong fuel pumps. I did a pressure test on the KE Jetronic /Fuel Distributor. On the lower chamber I get 5 bars and on the upper chamber with the EHA disconnected I’m getting 5.4 Bars. I ‘ve also replaced all injectors (Bosch x 6) and seals. I did not do an individual flow test to Injectors Vacuum I’ve done a Smoke Test and it shows no leaks in the Engine Bay. I carried out a Vacuum Pressure Test from the Intake Manifold. Interestingly it went from 14hg to 15 Hg floating between these points. (Have a Video if I could email it to you) I believe it should be between 18 to 21 Hg and steady. The Vacuum Dial at that pressure indicates Late Ignition Timing. I’ve also conducted a Compression Test and that indicated 13.5 Bars of Pressure on all six cylinders. Other Components Tested I’ve conducted tests on the following and all appear to be working. a) The E.H.A b) The ICV Valve c) Potentiometer d) Temperature Sensor e) Crank Shaft Sensor f) Micro Throttle Switch g) Sensor Plate h) HT Leads ( Measuring Resistance) i) Duty Cycle j) Air Intake Temperature Sensor I’ve run out of ideas at this stage and desperately want to get to the root of the problem. Really appreciate your time. Cheers
Tried to do flow test today. Was unable to place fuel lines into individual bottles. Took off all lines and bypassed FPR. Could hear it prime and all ports seem to be holding. No fuel in ports. Did a pressure test some time ago and it produced 2 litres in 1 minutes. I doubt its a fuel distributor problem. On to the next plan!!!
Thank you for all the information. My car is 230e 1992 m102. I tested CTS and the ohm measurements looks fine. You said the cold start injector must be active below 60C. But when it is not very cold (in my case under 10C) my cold start injector does not work. 4-5 seconds ignition and the rpm goes to 950 and then after warmup it falls to 800. I tested it with another CTS. I put CTS in a cold water and plugged it and then started the car. the cold start injector worked. The rpm went to 1200 and after warm up phase it fell to 800 rpm. Perfect. What can be the cause of the problem? When I park the car during the night and try to start in the morning it takes 4-5 seconds without the cold start injector. But if the weather is really cold that means below 10C, it takes only 2 seconds. Another difference is without the cold start injector the rpm is 950-1000 and with cold start injector active the rpm is 1200 during the warm up phase. I really can not understand the cause of the problem? Any help is really appreciated. All the best.
Hello, thanks. Have you replaced the O2 sensor? If the car behaves well while cold and starts stumbling, jerking, has bad idle when warm, then your issue can be O2-sensor. If you haven't replaced it yet, consider replacing it. These have to be replaced each 30k miles(50k km).

Do you need to test both poles in the two pin sensor? Mine reads fine from one pole, but nothing from the other pole. Does this mean that the sensor is bad?

Hi and thanks. Concerning the cts(coolant temperature sensor) - all contacts must give same readings-2 of them are for the engine and second two for the EZL.

Try testing the injectors. Take them out and put plastic glasses under each of them. Deflect the sensor plate for about 5 seconds and then measure the time. If the injectors don't drip fuel within 2 minutes, they are okay! I suppose you know how to turn the fuel pump on?
