Question about Mazda MAZDA6
1 to 2nd gear ****, down shift from 3 to 1 st gear. Obd scan no faulty code. Last times Po772 found.please help....thanks
P0772 is indicating that shift solenoid e is stuck in the on position in both the 4 cyl and 6 cyl engine transmissions. Outside of inspecting the fluid level and condition and then doing a line pressure test of transmission pressure, the next steps involve removal of the oil pan and valve body to determine if the solenoid is faulty electrically (open or short circuit) or if the valve it controls is stuck mechanically. Not something that average owner would want to tackle I'm afraid to report.

SOURCE: obd code p0304
P0304 is actually pointing to a misfire in cylinder 4, not a camshaft sensor problem.
There could well actually be two misfires rather than just one because Ford use a wasted spark ignition system wherein two cylinders are fired at once, one of them on its compression stroke and the other on its exhaust stroke, hence the wasted spark on the exhaust stroke.
You say it is "popping" which would lead me to believe that there is a spark issue rather than a fuel issue, because the popping sound would be the fuel igniting either in the exhaust or the intake rather than the cylinder, and this would be confirmed if you were to run the engine and then switch it off and pull the no.4 spark plug and it were to be covered in fuel.
If you were to find two plugs covered in fuel and the rest ok, then the coil pack feeding those two plugs would probably be the problem.
If only one plug were covered in fuel then either the plug or lead feeding that cylinder owuld probably be the issue.
If none of the plugs are covered in fuel, indicating a fuel problem, and you were to swap the no.4 injector with one of the other injectors, and then the fault code were to change to the cylinder into which you swapped the no.4 injector, then the injector would be the problem.
Very best regards

P2181 is a overheating engine.
Bad fan themoswitch, temp sensor themostat water pump impeller fan motor or fuse on battery
check to see if fans work by turning on Air Conditioner (fans should run with A/C on). Turn A/C off, warm engine, check to see if fans come on, if they do NOT it may be thermo switch on radiator on lower left side, has 3 wire plug, takes 1-1/8" wrench/socket to remove. This thermo switch controls fans when temp reaches 195F, if fans do not come on at engine temp 190-195F try replace switch VW part number: 1J0-959--481-A You can verify if the switch is bad by shorting wire 1 and 2 (fans should come on when jumpered).

Hi sounds like a problem I was starting to have in my 04 Accord. It would shutter terribly between gears. We had changed trans. fluid every 60k miles but evidently that wasn't good enough. I was shopping for a trans when I talked to my mechanic and he recommended new fluid. We drained and refilled trans twice and now drain and refill trans pan every other oil change ( about 20k w/ synthetic). After the fluid change trans. is doin great. Don't run and go pay for a trans flush at a local shop. I worked at a very highend dealership as a service writer and trust me it is a rip. In your honda you have drain plug just drain and refill, then run, repeat. It will do the same thing just takes a little longer. I have 190k on "The 04" now and it just won't quit! Honda's Rock!

OK, let me remember..........the code 753 means the solenoid INSIDE the tranny pan is bad. You don't have 1st or 4th gear, is what I was told, however, you probably WON'T even notice. I didn't. If you are at a stop, and get on it hard, you should be able to tell. If you drive normal, like me, and just accelerate gradually, you would not be able to tell that the truck is not hitting the 1st and 4th gear. You may not recognize a problem, just the check engine light. Your going to have to drop the tranny pan, replace the solenoid, and reinstall the fluid and the pan. The hardest part is, upon dropping the pan, if you don't know what you are doing, you can damage the other solenoids, and if you don't damage any, you may still have a hard time realizing which solenoid is the right one. It would take 1hour at, plus tranny pan gasket and fluid, etc., etc., for a total of about $120. Most transmission shop charge $100 for a transmission oil and filter service. The solenoid was about $20. It is not hard to replace, just unclip the wire harness and solenoid which will be an extra 5 min to the service time.
