I have not noticed a drop in preformance. Efforts to track outgoing civilians underway. So I put sensor 1 back in, and ordered a new generic Bosch 0281002710 sensor and put it in for sensor 2. This includes vehicles made since 2005 such as Ford trucks using 6. I then got the error codes about implausible signal for both sensors. The generic Bosch sensor is much cheaper to buy as well.
I'm going to clear it and see if it comes back. Thermal stress can distort the head and make it swell in areas that are hottest like those between exhaust valves in adjoining cylinders, and areas that have restricted coolant flow like the narrow area that separates the cylinders. I decided to replace the easier of the 2 sensors the one by the hood support strut as shown in the above picture. I'm in no way a complete noob on changing parts out but sensor wise and whatnot I'm lost. It is really that simple.
Investigation into the cause of the initial compromise is underway. Actually the car has over 44,000 miles on it. They proceeded to tell me that there were four pressure sensors in the exhaust system and it was impossible to tell which one failed based on this code. I should have read the warranty page and stayed away from the Dealer like so many here have said. Also the 09 model will not work with the B model sensors even if you have two matches ones at least my vehicle did not like it. .
If terminals are corroded, burnt, or possibly green than its normal metal color, then that means a problem. So it had to be the other sensor. The exhaust pressure feed lines must be intact, not leaking, not plugged or bent. You can sign up through our website or by calling us at 1-800-701-6230. Are there any suggestions on possible solutions to fix this? Also should i just replace sensor B only, or both sensor A and B to save labor cost. Make sure the tube connects to the turbochargers of the intake manifold, and there is no leaking.
I took my old sensors and checked the resistance between pins 1 and 2 and between 2 and 3 and found that the sensor 2 behind the oil filler cap was open loop infinite resistance on both sets of pins. It is mounted to a bracket which needs to be removed. Don Follow on, since this thread is the first to show up searching for P047a I replaced my sensor, 1 in the following diagram. The voltage will increase in a linear fashion as exhaust pressures increase. Note: This is a critical step. Any and all help is greatly appreciated! It stems from an exhaust back pressure sensor not working correctly.
Optimizing this mixture means better fuel economy and fewer exhaust emissions. The hoses are held onto the barbs with some spring hose clamps. At least in my mind it shouldn't. This code is exclusively concerned with the incoming signal from the exhaust pressure sensor not being able to match the intake manifold pressure or ambient pressure key on. Definition This error code is a generic trouble code that applies to all engines equipped with variable nozzle turbochargers both gas and diesel. If the problem comes back replace the other one with the one you removed before, reset and try again.
The codes indicate a potential problem with the G451 Exhaust Pressure Sensor 2 signal implausible or wiring open circuit. Is there any reason behind this? Access to Incident Report denied without O5 clearance. I swapped the sensor back thinking that if it is both sensors, I can buy another one and swap it out quickly. Contained: see Incident Report P047A-03-2010. Locate the G451 Exhaust Pressure Sensor 2 below a heat shield near the oil filler neck. This will usually cause the head gasket to leak compression between adjacent cylinders, or leak coolant into the cylinders.
The first one was the exhaust flap which was repaired under the 3 year 36,000 mile warranty. Compromised Items: Propionibacterium 047-A, Streptococcus 047-C, and Clostridium 047-A. The generic Bosch sensor is much cheaper to buy as well. Common mistakes when diagnosing the P0472 code The most common reason the P0472 code gets misdiagnosed is because it gets confused with an exhaust gas recirculation code. If the tube is free of carbon buildup, then check the connectors and wirings and look for signs of damages, such as chaffing, rubbing, burnt, or bare wires, spots, or plastics.
