Usually with this kind of problem, the direct impact can be seen on the engine performance. Affected fuel consumption, engine stalling and non-responsive during acceleration are the first signs along with Malfunction Indicator Light illumination. OBD Code P0417 directly points out to the problem with the air injection system and thus needs immediate treatment.

A stored code P0417 means that the powertrain control module (PCM) has detected a short in a secondary air injection system switching valve circuit. This particular switching valve has been given the designation B and refers to a particular switching valve in a system that uses multiple switching valves. A shorted circuit could mean that the effected circuit has come into contact with an unexpected voltage signal or a ground. A shorted circuit will usually result in a blown fuse.

The PCM receives voltage input signals from pressure sensors to monitor fluctuations in SAI system pressure. When appropriate conditions are met, the PCM electronically opens the necessary valves and allows secondary air to be pumped into the exhaust system. The PCM monitors SAI pressure sensors and activates the pump when required in vehicles that are equipped with electric pumps. If the PCM detects a voltage input signal from the SAI switching valve B circuit that is indicative of a short (to voltage or ground), a code P0417 will be stored and a malfunction indicator lamp may be illuminated.

What causes this problem with the Secondary Air Injection System Switching Valve B Circuit Shorted?

• Damaged or faulty air pump
• Poor electrical connection and wiring
• Short or open connection to the harness
• Damaged Check valves
• Faulty injection valve relays

1. Air Injection Pump - OBD code P0417 can occur due to faulty air pump leading to water entering the system. Replace faulty pumps now!
2. Air Control Valve Relay - Check for faults in the valve relay and replace it immediately. Buy new relay from us!
3. Air Injection Check Valve - Valves can be damaged and can cause wrong air flow in the injection system. Buy quality air injection check valve now!
4. Diagnostic Tools - A qualified mechanic will need quality diagnostic tools to resolve this OBD error. Buy new tools from us at exciting prices.

Interested in knowing the symptoms to OBD code P0417? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with this fuel injector problem.

Common Symptoms

• Check Engine light on
• Engine hesitation on acceleration
• Unusual noise from the secondary air injection system
• Engine stalling and rich conditions

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue, you need to follow certain steps, and to solve OBD error code P0417, you will need to undergo the following replacements:

• Air injection system pump replacement
• Air injection system pump check valves replacement
• Repair/replacement of lines going to and from secondary air injection system pump

Apart from the fuel injector, you might need to undergo few more replacements. You might need Air Injection Pump, Check Valve, Indicator Lamp, Sensors and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination.

Here are some steps which you should follow in order to diagnose this fault code:

• Scans codes and freeze frame data in order to verify the problem and check if the code is really present.
• Clear the code and retest the vehicle under similar conditions to see if the error reappears.
• Visually inspect all the associated wiring for the air injection system and repair as necessary.
• After clearing the code, a test drive will reveal if the P0417 returns immediately.
• If it doesn’t, the issue could be intermittent or temperature dependent. If it does return, a fuse may be blown and your mechanic will check that next.
• If the fuse is fine, chances are high the pump itself is defective and will need to be replaced.
• Check PCM for faults and replace or reprogram as required.

Common Mistakes When Diagnosing the P0417 Code

Sometime the individual fails to inspect and repair the one-way check valves inserted in the hoses leading to the exhaust pipe. If the pump is replaced with a still defective valve, chances are high the pump will fail shortly after.
