Faulty or contaminated bank 2 exhaust temperature sensor giving an implausible reading; Damaged wiring, corroded pins or a poor connector on the bank 2 temperature sensor circuit; Exhaust leak near or upstream of the bank 2 sensor, giving false temperature readings; Bank 2 combustion fault such as a misfire, faulty injector or boost or air leak, causing abnormal exhaust temperature; Restricted or failing bank 2 catalyst or particulate filter, causing abnormal temperatures; Fault in the engine control unit or outdated software, where a manufacturer bulletin confirms it for that engine.

What it means

P1462 on a Volkswagen means the engine control unit has judged that exhaust gas temperature control on bank 2 is out of range or not performing as expected. It compares the measured bank 2 exhaust temperature with the value it expects from the engine's load and operating conditions, and it sets the code when they disagree. Which sensor and control strategy are involved depends on the engine, so check the model-specific wiring and data.

Symptoms

Engine warning light on
Reduced power or limp mode on some engines
Rough running or hesitation under load on one bank
Increased fuel consumption
Possible failed emissions test
Particulate filter regeneration problems on diesel models

How to diagnose

Read all stored and pending codes and the freeze frame data, noting engine load, speed and temperature when the fault set.
Check for related codes such as misfires, fuel trim, boost, sensor circuit or particulate filter faults, and deal with those first.
Visually inspect the bank 2 temperature sensor, its wiring and connector for heat damage, chafing, water ingress and corrosion.
Check the exhaust on bank 2 for leaks, cracks or loose joints around the sensor and upstream of it.
With the engine cold, compare bank 2 sensor live data with bank 1 and with ambient temperature, then compare them again under load.
Check the sensor circuit for continuity, short circuits and supply voltage or resistance against the model-specific figures.
Check for misfires, injector faults, boost or intake leaks and fuel trim differences between banks.
Check manufacturer service information for software updates or known faults on that engine and model year.

How to fix

Replace the faulty bank 2 exhaust temperature sensor.
Repair or replace damaged wiring, terminals or the connector.
Repair the exhaust leak and renew any damaged gaskets or sections.
Fix the underlying combustion, injector or air leak fault on bank 2.
Repair or replace a restricted or failed catalyst or particulate filter once the root cause is found.
Apply a software update only if service information lists it as a fix for this fault.

Can I keep driving?

Medium severity

The car can usually be driven carefully for a short time while you arrange a repair. Stop driving if the engine goes into limp mode, runs roughly, or there are signs of overheating or a blocked exhaust, as the catalyst or filter could be damaged.
