Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. What does this mean? The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system. P Mercedes-benz Description An air pump is used on the vehicle to lower tail pipe emissions on start-up.

The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves.

The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.

Why is the Engine Light ON? Home - About AutoCodes. Posted and Edit by AutoCodes.Plugging in the AUTEL diagnostics tool revealed a P fault code relating to secondary air injection, so I set about troubleshooting and fixing the problem. Remove front section of engine cover by lifting up and pulling forward. The way to disable the system is to remove and plug the single vacuum outlet the base of the clear thin pipe to the left in the picture above from the control solenoid to the air check valves, one either side of the v6,v8 and v12 variants, then simply pull the control relay from the right hand fuse board in the engine compartment.

Relay N. This will accomplish two things until you get chance to repair the system, although please note it will not extinguish the engine check lamp. Mercedes — Secondary air injection pump. From this it can conclude that the secondary air circuit is functioning correctly — engine management is happy!

The reason it checks in this manner during the drive cycle is it can effectively test out all components in the circuit in a few seconds, air pump, air supply piping, electrical controls, check valves and actuating vacuum etc. If even one of these control sections is giving issue, then its comparative live testing will result in a fail and flag the P fault code.

Both control relay and fuse located in right hand fuse board. At the same time the electrical solenoid controlling the check valve vacuum is energised, allowing vacuum to pull open both diaphragm caps. Only after the engine has warmed up and at some further point during the current drive cycle will the system be checked once more for correct operation.

MB part No. A Has built in coil suppressor resistor. Bosch Part number for this item cross references to: BOS Secondary air injection protection fuse 40A — Fuse Orange Maxi-fuse. There are several faults that can occur to raise the P code and resulting amber warning lamp, but often it is down to a failure of the secondary air pump itself. Once the silver contact area of the relay has deteriorated unreliable operation will result.

Worst case is that the relay sticks on and the air pump remains powered beyond its 90 second period and running continuously to its final destruction. Relays in this circuit as well as ones in the Air-matic circuit should, in my view, be changed as a service item every 50k or so miles to attempt to prevent costly pump repairs.

The resulting maths is simple.Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Even though the vehicle is parked, a signal being varied is sent from the fuel level sensor to Engine Control Module ECM. P Mercedes-benz Description The fuel level sensor is mounted in the fuel level sensor unit.

The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor.

The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. The fuel level is monitored during vehicle operation to ensure conditions are meet for the misfire detection monitors to run. The level sensor output can be tested with an oscilloscope when removed from the fuel tank. Get Access to Factory Service Manuals. Need more help?

Why is the Engine Light ON? Home - About AutoCodes. Posted and Edit by AutoCodes.Simeon answered 6 years ago. I was driving down the road and the car did not want to accelerate after a while of driving. I had to cut the car off and let it sit for a minute.

I proceeded to crank the car up, which it did. I have a check engine light fault that came on 11 months ago. It came on after an electrical failure of one of the control boards.

The inital fault code pointed to the balancer in the engine. How reliable are these cars? Am I likely to need major repairs in next 2 years? I have buddy that knows Mercedes but not 4wd. His thing is older Mercedes early 80s late 70s.
