P1346 and p1351 code from toyota sienna 2001, new timing belt

Two are VVT, one is IAC. Fix them, clear the codes.

I think the engine is misfiring because of cam position sensor.These can be the possible causes :
- Faulty Intake Camshaft Position sensor
- Faulty Camshaft Position Solenoid Valve
- Engine mechanical condition - Valve timing off
- Intake Camshaft Position sensor harness is open or shorted
- Intake Camshaft Position sensor circuit poor electrical connection

A blast from the past (fav. movie)
i love caps, snaps me back to my first home computer (Northstar z80)
and my silly ASR33, printing terminal, caps only, flash ! im there....
misfires on all 6 cylinders. if patient,.
what car? what engine? what year?
1150 AFR bad.
1346 VVT says, cam is bouncing like MAD (DEVIATIONS) bank1
1349 VVT frozen, means it can change it ,but how could it if it bounces. bank 1
1351 VVT Sensor Range/Performance Problem (Bank 2)

here is my guess , your engine is????
2.5,3.0,3.3,3.4,4.0lilter engines,

new belt ,why old one snapped or shredded? or worse slipped?
my guess, bad belt setup, not timed right. or bad tensioner. bad idlers, or
or bad VVT parts, or bent head valves.

the V6 may be interference, and TOY dont say, but Gates lists most 96 and newer as Interference...engines.
i will assume it is (this is 1st deal with me, as im ,FIRST do no HARM"
and these engines , what do i do?
i do a leakdown test, just after the belt is replaced and tensioned, turning engine by hand.
if the leak down test FAILS the belt snapped and the valves did hit.
this i do everytime, it takes me, what 30 more minutes?
this act prevents further damage to head and pistons and rod bearing.
the damage can cascade fast to needing a new engine. now..
IMO, good luck.

It is highly possible,

P1346 Variable Valve Timing Sensor / Camshaft Position Sensor Circuit Range / Performance, but I am not sure.


You can get a Mini VCI to clear code, it is widely used in Toyota cars. and really a cheap tool.

P0330 Knock Sensor 2 Circuit (Bank 2)
P1133 Air/Fuel Ratio Sensor Circuit Response Malfunction (Bank 1, Sensor 1)
P1135 Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
P1346 VVT Sensor Range/Performance Problem (Bank 1)
P1349 VVT System Malfunction (Bank 1)
P1351 Variable Valve Timing / CMP Sensor Range / Performance
P1354 Variable Valve Timing System Fault

NOTE:Variable Valve Timing (VVT) sensor is also known as camshaft position sensor.
The Variable Valve Timing (VVT) system controls intake valve timing in response to driving conditions.

Possible causes are:

1. Incorrect valve timing P1346, P1349, P1351 & P1354
2. Faulty oil control valve P1346, P1349, P1351 & P1354
3. Faulty VVT controller assembly P1346, P1349, P1351 & P1354
4. Faulty ECM All Codes
5. Jumped timing belt All Codes
   
6. Faulty Camshaft Position Sensor P1346, P1349, P1351 & P1354
7. Faulty O2 Sensor (Bank 1, Sensor 1) P1133 & P1135

CALL YOUR LOCAL AUTO ZONE-THEY CAN LOOK UP THE CODE FOR YOU

have diagram on how to replace has instructions and images to replace belt, need email address to send to

P1346 is the code for:
VVT Sensor /Camshaft Position Sensor Circuit Range/ Performance Problem (Bank 1)
If the code came on just after the timing belt replacement more than likely the sensor was damged in some way during the work. The sensor is located in the same area the mechanic was working in while changeing the timing belt. You should have this checked right away. A faulty cam sensor can also lead to the vehicle not starting.
