Electric fault tracing Special tools Measurement of charge air temperature sensor 1. Undo the charge air temperature sensor con- nector. 3b.Or use a multimeter to measure between pins 5 and 6. The multimeter should show 18 -22 Ω. Diagnosis tool* with cable 885 2931 Tool for removing fuel and oil filter 999 91796. Measurement of engine speed sensor 2. Use the multimeter to measure across the two contact pins on the sensor. The multime- ter should show the following values at: * Order the cartridge separately, part number 885312 60° C .................................................... 1240 ± 42 Ω 120° C ......................................................
195 ± 10 Ω 90° C ...................................................... 458 ± 20 Ω NOTE! The sensor is highly sensitive to temperature changes. It is enough to breathe on it, or hold it in your hand to get an incorrect measurement value. Data cable* for diagnostic program 885337 Multimeter 951 00608 * When you order the data cable, an order form is enclosed for software. 4. Use a multimeter to measure between pins 3 and 4. The multimeter should show 0.8 – 1.2 k Ω .
