Problems:

Overheating

The 1991 Toyota Previa with the 2TZ engine is prone to overheating issues, often due to a failing thermostat, a malfunctioning radiator, or a water pump that needs replacement.

Head gasket failure

The in-line 4-cylinder configuration can sometimes lead to head gasket failures, especially in older models. This can result in coolant leakage and engine overheating.

Timing chain wear

The timing chain in the 2TZ engine can wear out over time, leading to poor engine performance and potentially causing the engine to misfire.

Fuel injection problems

As the engine uses electronic fuel injection, issues with the fuel injectors or the fuel injection system can arise, leading to poor fuel economy and engine performance.

Oil leaks

The seals and gaskets in the 2TZ engine can degrade over time, leading to oil leaks. This can result in low oil levels and potentially serious engine damage if not addressed.

Crankshaft position sensor failure

A faulty crankshaft position sensor can cause the engine to stall, misfire, or not start at all, as it is crucial for engine timing and operation.

Carbon buildup

The electronic fuel injection system can sometimes lead to carbon buildup on the intake valves, affecting engine performance and fuel efficiency.
