Nissan E13 / E15 / E16

Nissan's small four of the 1980s — the E13, E15 and E16 — in the Sunny, Sentra, Micra and Pulsar.

It is a simple overhead-cam engine from before engine management meant anything, carburetted on most versions and with early single-point injection on the rest. There is nothing to read with a scan tool on the carburetted cars and very little on the others.

So diagnosis is physical: compression, vacuum, ignition timing with a light, and fuel delivery measured rather than inferred.

Its recurring complaints are the era's — a distributor that fails with heat and gives an intermittent hot-restart stall, vacuum hoses that harden, and a carburettor whose many small passages block on fuel that has sat.

The GA family that replaced it is chain-driven and injected and has its own page here; the two share a model line and nothing else.

The turbocharged E15ET exists and is a different proposition from everything above.
