Disconnect from solenoid and apply vacuum to that pipe. One of the wires had 12 to 14 V but the other had no voltage at all. It is the sole responsibility of the viewer to assume this risk. In these cases, consult the manual to locate and identify all relevant components, as well as to determine the location, function, color-coding, and routing of all relevant wiring. Engine sensors that might share a reference voltage circuit could include the Fuel Rail Pressure Sensor, Crankcase Pressure Sensor, Camshaft Position Sensor, Inlet Air Pressure Sensor, Exhaust Differential Pressure Sensor, Boost Pressure Sensor, and sometimes, the Radiator Fan Control. I attached some pipe and a bike pump! The trouble with modern vehicles is the technology! Clear all codes after repairs are complete, and complete at least one drive cycle before scanning the system again to see if the fault returns. .
Disconnecting battery for 48 hours resets all these parameters…. Note however that while this symptom is not usually associated with code P02E9, it has been known to occur on some Ford applications when P02E9 is present. If they are, this can give the impression of lack of power. Turbo boost pipes Post turbo, the pipes will be or should be under pressure when the engine is being revved or driven. Easier to test with vacuum kit. How do you troubleshoot code P02E9? This is important — white with green stripe looks similar to, but is different to green with white stripe! Then start the engine, and at 2000rpm air should be blown out. Do I understand you wright when I say that the F-super cable works find in my transit? Odds are it won't be in plain sight and maybe hard to find.
Make repairs as required, clear all codes, and rescan the system to see if the code returns. This is entirely for emisssions control, but the side effect is all the crap in the exhaust goes back through the valve, back into the inlet manifold and makes a mess. Apart from a stored trouble code and illuminated warning light, other common symptoms of code P02E9 varies between applications and manufacturers. Sensors to measure intake manifold oxygen concentration have also been developed. Note however that on some applications, there may be only control flap in the plenum of the intake manifold that serves to control the flow of intake air throughout the entire manifold. Not saying it 100% was them, but it certainly happened when in their posession, so it was either them, the bodyshop they took the van to and left it there, or the tube-swapping-fairies.
Check the pipes to the air resvoire and ensure they are all spotlessly clean. Sensor originally equipped on your 2003-2015 Ford 6. Inlet Manifold The inlet manifold sits under a few bits, so see for instructions on how to remove it. At least this helped focus the mind…. Hi very informative article,glad you got your problem sorted. Testing procedures vary between applications, so be sure to consult the manual on the correct procedure to follow during this step, which generally involves checking to see that the actuator moves feely throughout its full range of movement.
Pin 4 should earth with no resistance 0 ohm Discount pin 3 as it works the iat sensor. This is on the off-side part of the engine attached to the bottom of the air-filter box. What are the common causes of code P02E9? If the engine is equipped with a mass air flow meter, it often incorporates a temperature sensor that can provide a measurement of pre-compressor intake air temperature. I took off and manually checked every pipe from the turbo to the inlet manifold. Check all pipes are in good condition and not split Simple, but worth checking 10. You may want to pick up a cheap vacuum test kit to see if there is sufficient vacuum at the turbo. All do-it-yourself projects entail some risk.
Turbo Inlet Remove the pipe from the air resovoire to the turbo inlet. This information could be useful should an intermittent fault be diagnosed later on. Step 1 Record all fault code present, as well as all available freeze frame data. Some friends helped me out for advice, and a number of guys on forum gave me pointers, accurate information, specific information and tips — one of which identified the swapped pipes. As such the pipes will be under pressure and leaks may become apparent.
No harm done, just frustraiting! It has 5 wires running to it. Characteristics of fault Bizzarely, the van drove quite well — on the flat Wiltshire! Never thought to use a clean. The temperatures should all be logically correct. Do not attempt to do anything that I have! Pipes are fairly easy to get off with the exeption of the ones connected to the turbo boost outlet! When installing, use care not to damage plastic locking tabs. So my question is should there definitely be a reading from both and do you or anyone know where these two wires go to as I have followed the wire with no voltage chasing it back to the right hand side looking at the engine behind the water coolant bottle but then loose where it goes. Also — with a cheap vacuum test kit you can test how much suction is required to move it — figures above.
While these restrictions resemble throttle bodies on gasoline engines in that that they consist of a moveable plate that looks like a conventional throttle plate, their sole function is to restrict the volume of air that flows into the manifold when it is partially closed. Any leak would give lack of power, so check carefully, and reassemble well! When driven, this was fine. Piezoresistive micromachined pressure sensors are common for these applications. Failing to replace a damaged connector cover will lead to a loose engine harness connection and ultimately a stranded vehicle. The exception is Pin 4 which should be earth and 100% continuity to earth at both ends.
Also clean and check the electical connectors. Note that not all of the sensors listed here will always share a reference voltage circuit, and that on some applications, some sensors not listed here might share a reference voltage circuit. Step 7 The steps outlined up to this point will resolve code P02E9 in nine instances out of every ten, but if the fault persists, or returns after a few drive cycles, it is likely that an intermittent fault is causing the problem, Be aware though that intermittent faults can be extremely challenging and time consuming to find and repair and in some cases, it may be necessary to allow the problem to worsen considerably before an accurate diagnosis and definitive repair can be made. Once removed be gentle as the element is very very fragile. It should not move much beyond rotating freely.
But I would say, can you compare against another Mondeo of same spec? This connector is located on your air intake track as well. So 100 is roughly 1000mb. If its clogged it will starve the engine of air and hence power. Air Filter A dull possibility, but check your air filter! All mine were in perfect condition but it was easy to see how pipes could split and not be evident from a visual test. Therefore, if a short circuit either to ground or battery voltage exists in the shared circuit, multiple sensors can be affected, which can produce drivability issues such as stalling, hard starting, stumbling or hesitation upon acceleration, rough idling, fluctuating idling speeds, and several others, depending on the application. Earth So… With ignition on pin 2 should read 5v and pin 1 should read 1.
