What is the code for secondary air injection?
Most of them have the same setup. This repair was to resolve a check engine light giving code P0410 – secondary air injection malfunction. The beginning of the video, I explain background on how I knew this was the necessary repair in this case (P0410 is a general code which may be triggered by various causes). This is a common Mercedes problem.
When is the p0410 Mercedes-Benz code detected?
Most auto repairs shops charge between $75 and $150 per hour. When is the P0410 MERCEDES-BENZ code detected? The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system. An air pump is used on the vehicle to lower tail pipe emissions on start-up.
What are all the codes on a Mercedes Benz?
Use an advanced OBD-II code reader to read and erase Engine CEL, Transmission, ETS, ABS, Airbag and other systems. There are also codes for other control units such as transmission, ABS, SRS, ESP, 4ETS, airbag, A/C. Mercedes-Benz can have up to 47 control units. You can NOT diagnose them with a simple OBD-2 scanner.
How does an air pump work on a Mercedes Benz?
P0410 Mercedes-benz Meaning. An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump.

Can a 2002 Mercedes Benz drive cycle be incomplete?
Also, one customer with a 2002 Mercedes was unable to complete the secondary air injection monitor until one evening he allowed his vehicle to idle for 5-20 minutes in his driveway. He then turned off his vehicle and restarted the vehicle the next morning and allowed it to idle for another 5-10 minutes.
What causes a Mercedes Benz to run out of air?
P0410 MERCEDES-BENZ Possible Causes. Faulty Vacuum hoses damaged. Faulty Air Pump inoperative. Air bypass solenoid harness is open or shorted. Air bypass solenoid circuit poor electrical connection. Air bypass solenoid leaking/blocked or stuck open/closed.
What is the error code on my split air conditioner?
LG Split Air Conditioner shows error code CH 38. Talked with LG Mexico and the error is for lack of Gas, it leaked out. Called in the Gas guy, refilled and found leak, and now the AC works again.
How is the rate of air change calculated?
Ventilation and air change rates are calculated on a per-person basis. If the number of occupants in a room doubles, the required ventilation rate or air change doubles. This rule can be useful for office spaces as the occupancy level changes.
How often should you change the air in an AIIB?
Similarly, the CDC recommends 6-12 air changes per hour for airborne infection isolation rooms (AIIB). If dealing with viruses or other airborne infections, it is therefore recommended to have a higher ventilation rate, in the proximity of 6-12 air changes per hour.
How to get rid of an error code on an air pump?
To get rid of this error code, you can do the following: 1 Replace both the air pumps and the one-way check valve 2 Try and clean the air pump and test it. The one-way air check valve must be replaced as well 3 Replace the inlet hose of the air pump 4 Replace the fuse of the air pump (you can find it under the hood)
Do you need to replace the air pump in a TSB?
TSB will require replacement for the air pump and the installation of a new secondary injection hose. Simply replacing the air pump will not always solve the problem, as a matter of fact, it may come back over and over again. When replacing the air pump, it is important to clean the hoses and replace he one-way check valve.
What is the code for the air injection pump on a Toyota Tundra?
After looking online I saw it’s a pretty common problem on Toyota with the secondary air injection pump seizing. I checked it with the code reader at a local shop and the guy confirmed it, code P2240 “Air Injection Switching Valve Stuck Open Bank 1.”
I’ve never seen a code for a secondary air injection system before…. 2008 toyota tundra 5.7, 104,000 miles. I got a p0415 code. I replaced both pumps and the switching valves. Also replaced the battery and fuel cap. All fuses, including the main fusable link, and all check good with 12+ volts to each side.
How does the secondary air pump and relay work?
Filtered air is drawn from the engine air cleaner assembly. The powertrain control module (PCM) monitors the Secondary air injection (AIR) System for faults during cold start-up operation. When the system’s pressure or relay circuits operations vary too far from the predicted values, a DTC will set.
Why is the DTC p0418 relay’a’circuit not working?
The DTC P0418 is detected the the AIR vacuum control solenoid circuit not operating as desired by the PCM. An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module ( PCM) grounds the Air pump relay control circuit which energizes the Air pump.
What does the OBD II fault code p0418 mean?
What Does Code P0418 Mean? OBD II fault code P0418 is a generic code that is defined as “Secondary air injection pump relay A -circuit malfunction”, and is set when the PCM (Powertrain Control Module) detects a failure or malfunction in the SAI ( S econdary A ir I njection) circuit that is associated with the relay labelled “A”.
Depending on the car manufacturer, the code’s definition may change. As was mentioned, the secondary air injection system reduces emissions by introducing fresh air into the exhaust system.
Where is the IAT sensor in the intake manifold?
It can be located on the air cleaner, in the air inlet tube, or in the intake manifold. The IAT sensor is a two-wire sensor with a negative temperature coefficient resistor positioned so that it reads the air entering the engine.
What is the code for the intake air temperature sensor?
Meanwhile, a sensor that produces a low voltage input merits the trouble code P0112. P0098 is the mirror image of P0113 since it reports the same issue of low temperature, higher electrical resistance, and high signal voltage in sensor 2, the second IAT sensor in the engine.
What is the diagnostic code for an IAT sensor?
The fault may lie in other parts of the IAT circuit, such as the connection. If the sensor is faulty, a replacement part can cost anywhere between $1.94 to $110.93 on CarParts.com. There are other diagnostic trouble codes that cover the IAT sensors and their attendant circuitry. For example, an intermittent IAT sensor signal falls under P0114.
