NAS 110 3.9L Fault Code '20' What is this?

[jimbobwae]

Got a check engine light and the display is code 20. I'm not seeing this in the list of standard codes.
Does anyone know this and the issue?

Weird.

Could it be 28......and you have a faulty display?

28 indicates Check for air leaks in the following areas: * Hose, air flow meter to plenum * Breather system hoses to plenum * Brake servo hose * Vacuum reservoir hose (fresh air solenoid) * Distributor vacuum advance * Hose, purge valve to plenum * Injector seals * Any of the joints and junctions.

Rocky, thanks for the reply - I have a faulty eye-brain connection. It’s actually code 02. Did the six second disconnect and the display reset - all good.

I love it. I needed a ROTFLMAO moment.
