Reset and as soon as a code pops up read it and start there.

One fault (eg bad coil) can sometimes cause a number of codes. I had one bad coil which was throwing 5 "bad coil" codes. I have a cheap code reader - the dealer has the Toyota Techstream reader which may be able to discriminate/diagnose better.

Clear them out and see what pops back up. If you have a bad coil, the engine will be misfiring badly. If you can't feel it misfiring (shaking/vibrating/ loss of power), you probably don't have any bad coils.

ok cleared them and only p1354 comes up for now

Very possibly VVT sensor.

O1GS43O

correct sir it was the VVT-I control valve

O1GS43O

now i get code 1130 1135 0125 new o2 sensor on the way

O1GS43O

o2 is in now i just have p0325 Knock Sensor Circuit Malfunction,
p0330 Knock Sensor 2 Circuit Malfunction (Bank 2)

need to find the resistance spec of the knock sensors and harness so i can test them. anyone know?

i cleared the codes every day. today i put in the new o2 and cleared the codes after 8 mines of driving the p0325 and p0330 codes came up.

Have you reset the ECU? It's a good idea to "introduce" new parts with a reboot.

O1GS43O

i cleared the codes but i didnt disconnect the battery. lol maybe i should have done that.

the battery is disconnected now cause i removed the intake to get to the knock sensors and harness. just waiting for someone to let me know how to test the harness and sensors so i can order what new parts i need and put her back together.

O1GS43O

come to think of it i did disconnected the battery after i put in the vvti control valve but not after the O2 sensor.

O1GS43O

ok put the new knock sensors and harness in. only took me about 1:20 start to finish. now i have a p1150p code but i pulled the batt cable. ill drive it tomorrow to see if the pending code comes back.
