98 gs 4oo codes p1346 the car shakeing when in drive and when i slow down


it is a variable valve timing performance code. it could have a bad actuator solenoid, a bad cam actuator, low oil pressure or clogged passages, a wiring to control solenoid problem, or a bad controller. most often it is an actuator solenoid at 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

Check engine light code p1349


Code P1349 VVI Malfunction Bank 1. Bank 1 the difficult side where the intake body is.

This could be from a slight misfire from poor air. Ensure that the gas cap is on fully and not airtrapped.

1999 gs300 shows code p1349 and the engine runs really rough at idle , runs fine off idle


Its a Oil Control Valve most likely. Get the valve. Its like 100 from Lexus. Mine did the exact same thing with that code. GS300

Car will not idle 2002 lexus gs 300


if it drives fine off idle then I would suspect the Idle air control valve.
If its hard to start unless you put your foot slightly on the gas then again I would suspect the IAC
