    ,— lntake Air Temperature (TA)/ Coolant Temperature (TW) Sensor 1. Disconnect the connector, then remove the TA/TW sensor from the intake manifold/cylinder head. 2. To test a sensor, suspend it in cold water and heat the water slowly. Make sure more than half of the connector is submerged. Measure the resistance be- tween the terminals. STANDARDS: ores—1‘34 m a 40°C (95°F) 0.22—0.35 m at 30°C (173°!) DIGITAL CIRCUIT rEerR TA SENSOR 3.

CYL Sensor Inspection 1. Disconnect the connector of the CYL sensort 2. Measure the resistance between the white terminal and red terminal at the sensors Resist-nee should be: 055—035 Itfl 3, Measure the resistance between the White and Red terminals and crank angle sensor housing. R Inca should I: 100 kn or mo TDC Sensor Inspection 1. Disconnect theconnector of the crank angle sensor. Measure the resistance bemeen the brown terminal and blue terminal at the sensor. Resistance should be: 0.65—0.35 k9 3. Measure the resistance between the Brown and Blue terminals and crank angle sensor housing. Resistance should be: 100 kSZ or more 11-30
