What are the common causes of code p1494?
What are the common causes of code P1494? Typical causes of P1494 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring in the LDP Switch Control Circuit, or in one or more control circuits of sensors that supply input information to the LDP/PCM.
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 causes a p1494 leak in a PCM?
Typical causes of P1494 could include the following-. Defective Leak Detection Pump. Damaged, burnt, shorted, disconnected, or corroded wiring in the LDP Switch Control Circuit, or in one or more control circuits of sensors that supply input information to the LDP/PCM.
How to diagnose EVAP leak detection pump p1494?
NOTE #3: Apart from a repair manual for the application being worked on, a graduated vacuum gauge is required item to diagnose P1494 accurately. Record all fault codes present, as well as all available freeze frame data. This information can be of use should an intermittent fault be diagnosed later on.
What do you need to know about 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.

Typical causes of P1494 could include the following-. Defective Leak Detection Pump. Damaged, burnt, shorted, disconnected, or corroded wiring in the LDP Switch Control Circuit, or in one or more control circuits of sensors that supply input information to the LDP/PCM.
What causes a car to fail the emissions test?
More common trouble codes that cause vehicles fail on emissions test and make the Check Engine light coming on can found below. Even fouled or the worn out catalytic converter is the most cause failed on test, based on above data you will get a somewhat different picture, if all of the related codes by system or component to be combined.
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.
