Attach an external high quality tachometer to the engine speed detection connector on the harness side (such as 2. Compare the readings of the vehicle tachometer and the external tachometer at every engine speed, and check if the Standard value: FUEL LEVEL SENSOR CHECK M1543001200290 Remove the fuel level sensor from fuel tank. (Refer to GROUP FUEL LEVEL SENSOR RESISTANCE 1. Check that resistance value between the fuel gauge terminal and ground terminal is at the standard value when the fuel Standard value: • Point "F": 3 − 10.1 • Point "E": 90 − 110 2. Check that resistance value changes smoothly when the float moves slowly between point 3. If all checks are correct, go to fuel level sensor float height check. If any check is not correct, replace the fuel level Engine speed (r/min) Indication allowance of 700 600 − 800 2000 1900 − 2150 3000 2900 − 3225 4000 3875 − 4275 5000 4875 − 5325 6000 5875 − 6200 ACX00776 AB TACHOMETER ENGINE SPEED PAPER CLIP ACX01779 AC POINT "F " POINT "E " |
