When does code p1494 set in Powertrain Control Module?
When does code p1494 set in Powertrain Control Module?
Note however that the above definitions all have the same basic meaning, which is that code P1494 sets when the PCM (Powertrain Control Module) has detected a malfunction in the LDP ( [EVAP] Leak Detection Pump) itself, as opposed to when a leak in the EVAP system is detected.
What is code p1494 for leak detection pump?
Nonetheless, as stated before, code P1494 is less concerned with leaks in the EVAP system than it is with whether the Leak Detection Pump is working or not.
What are the symptoms of stored trouble code p1494?
Apart from a stored trouble code and an illuminated warning light, the only other noteworthy symptoms of code P1494 may be the presence of a strong fuel odor as vapors are released from leak sites, and that the vehicle may not pass an emissions test. Note that this code very rarely produces driveability issues.

When to use code p1494 on a pressure pump?
Thus, if the PCM detects that the state of the reed switch ( aka control switch) has not changed when a self-diagnostic cycle starts due to a failure of the diaphragm, the control solenoid and/or its control circuit, or the control switch, it will set code P1494 and illuminate a warning light.
