B3464 Toyota Avalon Ii Diagnostic Trouble Code
B3464 Toyota Avalon Ii code definition:
B3464 is a kind of OBD-II Diagnostic B-Body Diagnostic Trouble Code for Toyota Avalon Ii.
B3464 Toyota Avalon Ii is defined as Knock Sensor Circuit Range Performance (Bank 1 or Single Sensor). This refers to camshaft timing, which in this case is over-retarded. This is because the barometric pressure sensor is part of the MAF sensor. Sometimes, the MAF's sensing wire can accumulate and get covered with dirt, dust and/or oil residue, which can also lead to the error code.
Symptoms
Symptoms of a B3464 Toyota Avalon Ii diagnostic trouble code may include:
- Faulty or damaged wiring
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Poor fuel economy
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

Possible Causes :
- Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.
- Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses
- Crankshaft Position Sensor Circuit Performance Problem
- TP Sensor Learn Not Complete Problem
- Low Coolant Circuit Problem
- Cruise Control System - Vehicle Accel Too High Problem
- Kick-Down Switch Failed Short Problem
Repair Processes :
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
You might continue by connecting the scanner to the vehicle diagnostic connector and retrieving all stored codes and freeze frame data.
