How i clean the TPS sensor of a ford escape xls 2011 2,5 Lt l4 mecanic


it sounds like it's the idle air valve this controls the idle and drive rpm's when you step on the gas does it sometimes at idle go up & down by itself repeatedly? it could be something hitting the throttle and when you press down on the gas or shift it is knocked out lowering to normal idle/rpms, the tps is on the throttle body and is connected to the throttle lever and most likely right on the other side of the lever a little switch with a electrical plug on it search it so you can see what it looks like if you don't know already they are sealed and can not be cleaned you must replace it try checking with the car in park engine running and raise the idle by the throttle lever if it goes smooth up and down return to rpms that's not it if it races or sputters and then raises up that's it or it could be both units are blown out needing to be replaced

I have a 2001 Ford escape xls 4x4 2.0 4cylinder and when driving down interstate at 75 mph in 5th gear my rpms are running at 3500. Is this normal or what would be causing this? It sounds like it needs a...


That is a typical RPM at that speed for most 6-speed 4 cylinder engines. The reason for this is that they have a much lower power output at lower RPMs (due to lack of torque), and the engineers want for you to have SOME acceleration to get up little hills.

Revs seem higher than normal in my 2005 Suzuki Swift Sport (3.3rpm in 5th @ 100km/hr) - is this normal? I also have a really high fuel consumption rate


2 issues,
1: MPG, you failed to say MPG, 15mpg? or 39? is 39 low?
what MPG? you never said it?

2: rpm cruise. (what drive line, A/T M/T ?) what tranny?
first google hit , is this it? this yours?
engine: 1.5-litre 4-cylinder petrol, 75 kW/133 Nm
Transmissions: 5-speed manual, 4-speed automatic, FWD

3300 RPM in 5th and 100km
if you wish to now what is normal, find the final drive ratio, listed in the FSM. Id say this is normal. typical of tiny engines, with low torque.at lower RPMs.

if you have the A/T and IF the trannywere to slip, the TCM will infact throw DTC codes, telling you it did.
IS IT? (scan tools show you this fact as might that glowing CEL lamp on the dash, on driving.

RPM
my 1.6L spins 3000 RPM , at below tranny options valve counts.
54/59mph (104km/hr = 59) 5sp MT.
64.6 4sp A/T (goes fastest due to more aggressive OD + axle ratio is lower.)
56/.53 2sp A/T
see how drive line effects RPM? so will your cars options.

91 Toyota MR2 automatic transmission when i full stop sometimes i step on gas RPM goes up but it feels like it`s still in neutral, i have to down shift before moving again. I can`t find what`s wrong.


i have somewhat of the same problem! when im driving my transmission sounds like it sticks in 2nd gear or something. and ill be driving down the hwy and in either goes into neutral or into a lower gear so my rpms go way up! like im revving it. but when i unhook the battery for a few minutes it seems to fix it for a while...any clue whats going on?

With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.
