The fault code of 34 means that the signal voltage of manifold absolute pressure(MAP) sensor circuit is low and degree of vacuum is high, whose circuit condition is the same as fault 33. *1. this is to make sure whether fault 34 is generated in the actual or interrupted condition, the generating conditions of fault 34 are: fault 21 has not been detected (the TPS signal voltage of throttle is high); the rotationl speed is less than 1200r/min; the reading of MAP signal voltage is less than 14kPa; the rotationl speed is more than 1200r/min; TPS is less than 20% (voltage is lower than 1V which is higher than that when throttle gate is closed).
