P2062 code definition

Reductant Supply Control Circuit Open

What the P2062 code means

This code means the Engine Control Module (ECM), or Powertrain Control Module (PCM), doesn’t see electrical current flowing when it commands the pump on.

What causes the P2062 code?

This code will set when the ECM wiring or reductant pump circuit has an open. An electrically open circuit is when electricity cannot flow through the wires that power the pump. This occurs because of a break in the wiring or what is called a high resistance in some point of the circuit.

What are the symptoms of the P2062 code?

A Check Engine Light will certainly be the primary symptom. Some manufacturers choose to place the vehicle into a reduced power output mode if any part of the catalytic converter system is faulty. Some consumers have reported drivability symptoms, although there are likely other issues causing them. The owner won’t be able to detect it, but there will be increased emissions of NOx (oxides of nitrogen) out the tailpipe.

How does a mechanic diagnose the P2062 code?

A mechanic should begin by connecting a scanner to the OBD II connector of the vehicle. The scanner will be used to check for all codes in the ECM; any freeze frame data and any current data that can give him/her an indication of the fault. At this point the mechanic will make a diagnosis or elect to perform pinpoint tests.

Direct testing of the suspected components should be performed. In this case it would be necessary to check for power at the reductant supply pump and check for a good ground connection. If power and or ground are not present it will be necessary to use a test light to check the circuit at multiple points to determine where the failure has occurred. If power and ground are present, the pump is likely the problem and will need to be replaced.

Common mistakes when diagnosing the P2062 code

The most common mistake is not checking to see if the test light has a good ground when performing pinpoint tests. It’s an easy thing to miss. The amount of current to light a test light is significantly less than what is needed to run a pump. For this reason it is necessary to supply an alternate power and ground to the pump with a jumper wire. It is very common that the ECM will supply enough voltage but not enough current to power a pump.

How serious is the P2062 code?

For the most part the code is not very serious. This code is part of the NOx reduction system mandated by the EPA (Environmental Protection Agency). Depending on your feelings about global warming, you may or may not be concerned about this code. Some manufacturers have elected to program low power output modes into the ECM. This can seem like there is a major problem with the vehicle when it is simply the manufacturer giving the owner incentive to have the reductant system repaired.

What repairs can fix the P2062 code?

Additional comments for consideration regarding the P2062 code

This code is only used on diesel powered vehicles with catalytic converter systems designed to limit the emissions of NOx. These systems are a recent addition to the emission control requirements set by the EPA. For this reason, many technicians haven’t yet had the opportunity to work on one of these systems. Adding the relative rarity of diesel powered vehicles in comparison to the number of gas powered vehicles on the road only adds to the challenge.
