The 2.3-liter Nissan TD23 diesel engine was assembled for a very short time from 1985 to 1995 and was installed on commercial vehicles, Caravan minibuses and D21 pickups. This power unit is the least common in a series of motors under the TD index.
The TD series includes internal combustion engines: TD25, TD27, TD27ETi and TD42.
The engine was installed on:
- Nissan Navara 1 (D21) in 1985 – 1992;
- Nissan Caravan E24 in 1986 – 1990.

Disadvantages of the TD23 engine
- The engine is very noisy and prone to vibrations due to the timing gear drive;
- The gears wear out by a run of 250,000 km and the valve timing goes astray;
- At about the same mileage, a pump or a gear block gasket starts to flow;
- On the electrical side, only the oil pressure sensor and crankshaft position are buggy;
- Detonation due to bad fuel cracks the bridges between the vortex chambers.
