RE: 2.3 DOHC motor - correct operating temp - thebanjoman - 07-26-2019 OK... The 2nd Scan tool is showing the same readings by comparison. But I realize now I may have made very large mistake. When I moved the coolant tube that houses the SENDER and the ECT SENSOR from the J18 to the J23 (This tube runs from the back of the motor to the front and into the radiator) I just moved the tube, KEEPING the ECT SENSOR for the J18 in place.. Well This MAY be the reason why the temps are being reported so high.. The ECT SENSOR is DIFFERENT between the J18 and J23 ( I looked it up at Rock Auto . comparing vendor part numbers) ECT on J18 motor (when in the Sidekick) is 3 wire ECT on J23 motor (when in the Aerio) is 2 wire Could the ECT itself that I have in now be bad, generating values that are reporting incorrect, IE high temps?

Suzuki done not use 1 ect. the 3wire version is 2 ECT's one for the PCM brain, and OBD2 and the second sensor is only for the gauge. 2 different cars, can I assume you car is all J18, wired? J18 PCM , J18 ECT, only this works the ECT is just thermistor, on the G16 300ohms is 180F. on the J18 I do not have the spec on it. but most cars and engines generations use different, ECT. you must not use the wrong ECT on that J18 PCM. if your PCM is dash 77Enn or 78Enn (nn is for transmission type.) here they are. https://fixkick.com/ECU/EPC-ECU96-98/all_other_years/sport/Sport_page1.jpg not sure on your plumbing. but the ECT must be at the rear of head exit hot water Port, and most be ECT J18, 1996 to 1998 (what ever car was , must be) size and pin counts are not all there is , what thermistor is inside matters MOST.

Coolant tube from J18 that runs from the back of the motor to the top radiator inlet , I kept ECT and temp sensor from J18 All wiring from the J18 has been used. All connections swapped for one. labeled when taken out and returned when motor installed. J18 motor mounts and all external brackets and existing power steering and A/C compressor .. Only Long block, injector rail, and injectors from the J23 has been used. I followed the exact same method that Matt Verley used in https://www.youtube.com/watch?v=8Gv67n53cUs&t=417s to do the engine swap. I now need to test the ECT sensor that I have in the motor. I have a second ECT sensor from the J18 engine I pulled out. I should see near the same OHMs reading at the same temps on BOTH. I'll report back on the sensor details. RE: 2.3 DOHC motor - correct operating temp - fixkick - 07-27-2019 perfect ! the j18 manual shows this (suzuki spec on j18) SMP just responded to my asking here. RE: 2.3 DOHC motor - correct operating temp - fixkick - 07-27-2019 the sensor is easy to test in a pan of water, even just 2 tests, room temp 20C and then 80c, using any DMM + ohms mode. safe and simple and not risk to car. the data I took on mine is here , see my charge see right columns ignore the 2 errors I made here, (blush) 5030 and 5200 (midnight typos,,,, https://fixkick.com/ECU/temp-sensors.html if you look on my chart those voltages may work. 180F , if you back probe the sensor you see 0.65 volts CD , way less is and overheated engine or bad ECT.(or wrong ECT or china $5 knockoff sensors) RE: 2.3 DOHC motor - correct operating temp - fixkick - 07-27-2019 all comments so far assume ECU is 77E or 78E coded ECU on tag.

I pulled the ECT to test in a pan of water. To 'plug the hole' I put the ECT from my other motor and tightened it up and let the motor run to temp. I got nearly the SAME results. To test the ECT in a pan I did the following. Aluminum pot Candy/Fryer type Thermometer that can range from 100 - 450 Meter set on Ohms at 2K , My meter does't have a 1K setting. Alligator clips to leads attached to the ECT. I cut a piece of a drinking straw to use as a shield of the middle lead so clips couldn't touch. Suspended the ECT with a wooden spoon and a clamp to keep it off the bottom of the pan and filled water up to the top of the threads and not the plastic. Here are my readings. I took photos of each temp reading. 120 degrees - .981 140 degrees - .631 160 degrees - .430 180 degrees - .302 200 degrees - .217 212 - full boil - .188 First of all I Picture you posted on IMGUR states at 140 degrees it should be 0.584 176 degrees it should be 0.303 -0.326 Would these readings be considered 'in scope' of what I should expect to see? I think so. And the fact that I was getting SIMILAR readings of the ECT I have in now. When I got the car I had a chance to pick up a known good PCM to have a spare for a decent price so I picked it up. I plugged it in this weekend and rand the engine up and got the same results. To me it validates the ECT readings I am getting. I've tried as many ways I can think of to validate the results, multiple scanners, multiple ECTs and multiple PCMs. All with the same results. I have also located a few others who have done the same swap with a J23 into their Sport. They will hook up a Scanner to their vehicles soon and will share their results with me. I'm trying to get the most information I can for comparison. |
