What does the p0458 diagnostic trouble code mean?
Diagnostic Trouble Code (DTC): P0458 P0458 code definition The P0458 code means that a specific part of the EVAP system purge control valve circuit has caused a voltage reading that does not match the manufacturer’s specifications, and is therefore malfunctioning in some way. What the P0458 code means
What does p0414 mean in Powertrain Control Module?
A stored code P0414, simply means that the powertrain control module (PCM) has detected a short in a secondary air injection (SAI) system switching valve circuit.
What is the p0414 secondary air injection system?
Other secondary air injection system trouble codes include P0410, P0411, P0412, P0413, P0415, P0416, P0417, P0418, P0419, P041F, P044F, P0491, and P0492. A stored code P0414 should not be considered severe. The SAI system is related only to exhaust emission reduction and is not vital to engine operation.
What are the symptoms of a p0458 EVAP trouble code?
Noticeable symptoms of a P0458 EVAP trouble code normally only include illumination of the malfunction indicator lamp (MIL), or “Check Engine Light / Service Engine Soon” light. Other trouble codes may accompany this code. In some cases there may be a smell of gas and/or a slightly decline in fuel efficiency. Causes of this DTC may include:
When is the p0448 code stored in the PCM?
The P0448 code is stored when the powertrain control module (PCM) detects that the circuit for the evaporative emission control system’s vent has shorted, or that the valve for this system is stuck in the closed position. When gas sits in the gas tank, it emits vapor.
What are the symptoms of a p0448 DTC?
Symptoms of a P0448 DTC will include Malfunction Indicator Lamp (MIL) illumination, you will likely not notice any other symptoms. Potential causes may include: Some steps to take to diagnose and repair this trouble code include the following: Check your fuses, there may be a fuse that powers the vent solenoid.
A stored code P0414, simply means that the powertrain control module (PCM) has detected a short in a secondary air injection (SAI) system switching valve circuit.
