Engine codes

[Pete Masterson]

On our recent trip to Buellton for the Southwest Birds rally, I had
an unexplained buzzer (that remained on for the final 45 minutes of
our drive) with no dash lights. On the way home, I had the "check
engine" light come on (with no buzzer). By the time I got the coach
to the side of the road and stopped, the check engine light went out.
In both cases, the gauges all were in the normal range, except that
the oil pressure was at about 40 psi (normal is 50 to 70 according to
the DD manual).

The code on the Stop Engine Light now reads "25" (no codes) and there
are several 'historic' codes reported on the Check Engine Light (most
recent first):
61 Injector response time long
22 TPS Circuit low

I suspect the following were generated when I experienced overheating
in May before I had the radiator core replaced.
43 coolant level low
44 oil temperature high

I suspect these were experienced before I purchased the coach:
32 sel short or open circuit
45 oil pressure low
44 oil temperature high
16 coolant level circuit high
31 (twice) Aux output short or open circuit (high side)
46 battery voltage low
13 coolant level circuit low

I was suspecting that the oil pressure gauge or oil pressure sensor
(or the circuits in between) might be giving problems. The oil
pressure gauge tends to 'lock' at about 40 psi for long periods of
time. Then will vibrate wildly over the upper 1/3 of the range on the
guage.

Does anyone have any thoughts on what the problem(s) might be?

pete,

1. Turn off all power. IE switch from inverter and Battery wait a little turn
back on, make sure the horn is off, this should clear all codes...Memory.
Hopefully you will just get "25" no codes.

With injector time too long I found that one of the pins at the connector to
my DDEC1 had pulled away.
