hey don't mean to "HI-JACK" but why start a new thread....i'm having trouble initially getting the motor to start on but whenever i get the 1jz running and it runs rough, my tach doesn't work yet but it's idleing pretty high i would guess around 1200-1500 rpm +/- and it's also missing and if i try to give it gas it bogs out and dies, if i try to creep into the RPMs the Rpms do rise but won't go higher than 2500-3k rpms(it begins to cut out and won't go higher, if i try to force it above that it bogs out and wants to die), soooo to me it seems like it's in limp mode. already checked and i am getting 12 volts at fuel pump.
checked for codes... i'm getting code 12... TSRM says cam sensors, crank sensors and ECU. i'll double checked the ECU for leaking caps and it's fine and also tested it on my buddies 1jz with no problems. so i researched forums and TSRM cause i would like to do is test the resistance in the cam and crank sensors and see if they're within spec before i go buy new sensors and find out that's not the problem but every where i go i'm getting different resistance ratings for the crank sensor...
2jz TSRM says:
CHECK RESISTANCE OF CAMSHAFT POSITION
Resistance:
Cold 835 – 1,400 ohm
Hot 1,060 – 1,645 ohm
CHECK RESISTANCE OF CRANKSHAFT POSITION
Resistance:
Cold 1,630 – 2,740 ohm
Hot 2,065 – 3,225 ohm
but in this thread the guys said he got his from TSRM also with different resistance ranges. according to the ranges above my cam sensors are fine but my Crank sensor is dead at 1133 ohms but with the ranges in this thread it's a good sensor... who's right? here's the link i got my INFO from
http://www.turbosupras.com/pdfs/JZA80 TSRM/IG (2JZ-GTE).pdf
can someone maybe test the Cold and hot resistance on their cranks sensors just so we can see what the 1jz cranks sensors are averaging at? cause i was going to buy another cranks sensor but i had the guy test both sensors he had for sale and his readings came back 1183 ohms and 1103 ohms... still pretty close to what i had but he pulled the sensors off spare motors., so who knows if they even work.
