What does code P2457 mean?
Exhaust Gas Recirculation Cooling System Performance
The trouble code P2457 can be described as Exhaust Gas Recirculation Cooling System Performance. A lot of unburned fuel was wasted and expelled into the atmosphere by the car engine before the introduction of the exhaust gas recirculation system to the vehicles in the 1970’s.
What are the symptoms of a p2509 engine code?
Symptoms of a P2509 engine code may include. Malfunction Indicator Lamp (MIL) illumination with P2509 DTC set Tachometer may fluctuate between 500 to 700 rpm when idling cold Check gauges light may illuminate and voltmeter displays 11 volts or less
What are the symptoms of a p0471 engine code?
Symptoms of a P0471 engine code may include: Unable to perform manual regeneration – burn off the soot out of the particulate filter. Looks like a catalytic converter but has temp sensors and pressure sensor probes inserted into it. If unable to perform regeneration, eventually may become a crank-no start.
How to test p2509 power input signal intermittent code Dodge?
Place the voltmeter on amps and install one of the test light probes on the battery negative and the other wire on the red ammeter probe. Install the black ammeter probe on a good ground. There should be less than 30-miliamps draw. If it is less stop here.
Is there a check gauge on the p2502?
You may also see the “check gauges” warning lamp and have a P2502 and/or P2503 DTC along with this one. Test the batteries for charge. Use a voltmeter and place the probes on both terminals.

What does the p0472 code mean on an exhaust manifold?
What the P0472 code means. A P0472 code concerns the incoming signal sent by the exhaust pressure sensor because it’s not coinciding with the intake manifold pressure or ambient air pressure. The problem is strictly related to an issue with the electrical circuit. It often occurs with the P0472 code as well.
