(Blue stripe) from the throttle body exhaust gas
recirculation
valve nipple and connect a hand vacuum pump to the
nipple. |

2.Start the
engine. 3.Measure engine vacuum at 2,500 r/min. Standard value: 51 kPa or more 4.Reset the vacuum pump to "0" (Release vacuum) 5.Using a stop watch, measure how long it takes for the vacuum gauge to reach 51 kPa. Standard value: 1.0 second or less 6.If it takes more than 1.0 second for the gauge to reach 51 kPa, the exhaust gas recirculation may be restricted and should be cleaned. |
