I’ve posted about this problem previously, thinking it had something to do with the transmission. Someone pointed out it could be the differential, and I had that inspected but there wasn’t a problem with it. It cannot be ABS related, because the vehicle isn’t equipped with ABS (’00 Montero). I’m being told this is the TPS ($200+), but that cannot be confirmed without using an ohmmeter. Before I go out and purchase an ohmmeter to confirm, I was wondering if these symptoms I experience are actually TSP-related. If somebody can shed some light on this, I would very much appreciate it.
The problem is intermittent, and do not happen all the time. It first started as a knock whilst driving at highway speeds…as if someone suddenly slammed on the brakes for 1 second and released them. It was quite hard and noticeable before, but now it's gotten very faint and doesn't happen very often. Then I started noticing something usual at WOT last night. The best way to explain the symptom is…imagine you’ve just driven over wet tarmac and gunned the throttle, causing your rear wheels so spin freely. Then as the tires dry up, they stop spinning, but spin every now and then, because parts of the tires are still wet, until the tires are completely dry. I suppose it’s like the transmission is slipping to some extent but not exactly. Then again, I’ve recently serviced the unit and have religiously changed ATF every 25,000 miles since the truck was new. I’m being told the TPS is faulty and cuts off, causing these symptoms. Does this sound like a good enough explanation? Could it need cleaning with electrical contact cleaner? Thanks!
