PROBLEMS WITH TPS SENSOR CODES BUT IS WITHIN SPEC, ANY HELP? MOTOR RUNS TERRIBLE AND WILL NOT EVEN GET ON PLANE. WILL RUN GOOD FOR SHORT BIT AND THEN RUN BAD. THEN RESET TPS AND IT RUNS GOOD FOR A MINUTE THEN GOES BAD AGAIN BUT SHOWS TO STILL BE IN SPEC.
May be one of the H/T boys will show up but it may be in spec but not all the time if it is giveing you a code. Sounds like it needs to be replaced.
What exactly do you mean by "trouble codes"? Are you getting an error on YDIS? That will only show up if the TPS is out of spec. What is your TPS voltage set at?
I have seen them develop a flat spot where the voltage cuts out and keeps them from getting wide-open voltage, but it should still get on plane.
THANKS FOR THE FEEDBACK GUYS BUT GOT BAD NEWS TODAY THE #2 PISTON HAS ZERO COMPRESSION.
THE TPS WAS SET AT I THINK .6. AND IT LET ME DOWN SEVERAL TIMES THEY WOULD HOOK IT UP AND GET READING AND RESET, IT WOULD RUN GOOD FOR SHORT BIT THEN FOUL AGAIN. HOPEFULLY YAMAHA WILL WARRANTY MOTOR UNDER OIL PUMP RECALLS. MOTOR HAD RAN COUPLE HUNDRED HOURS WITH FAULTY PUMP BEFORE RECALL REPLACEMENT. ANY GUIDANCE OR HELP WOULD BE APPRECIATED. THANKS.
THEY SAID THAT THE RING CAME OFF THE PISTON OR CRACKED. THEY DID FUEL TEST IT HAD 93 OCTANE, NO ETHANOL AND HAD RINGFREE ADDED. SO THATS OK. THEY ARE GONNA TEAR IT DOWN AND LET ME KNOW THE EXTENT OF THE DAMAGE. NOTHING REALLY KNOWN YET.
