Question about Dodge Cars & Trucks
Posted by Anonymous on
When diagnosing a multi code vehicle, you have to start with the lowest code number first. P0230 is a code for the lift pump circuit. This does not necessarily men the lift pump is bad. It means the circuitry has a problem. It's an electrical issue. Does the vehicle start okay and run?
The second code, P1594, is a code for the alternator is charging at too high of a voltage. You can easily check that by using a meter to check the battery voltage when the vehicle is running. Any over 14 3/4 volts is considered high.
The last code, P1693, is a 'chump code'.c it simply means that there is a code stored in one of the computers in the vehicle. The ECM is probably reading the PCU that has the P1693 because of the codes in the ECM. Anyway, if you get through the first 2, P1693 will stay off when the codes are cleared.

your code is PCM/ECM power input signal intermittent. this is ussually a sign of a bad connection whether it be in a connector or a short or brake in a wire.

this obd2 trouble code table can help you understand the meaning of code, for this code, you can try:
Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.
