Default What do these codes mean for me?

P0321 Spark Ref

P0341 Cam Crank Error

P0705 Trans Range

P1361 IGN Control CIR

P1558 Cruise System

P1406 EGR Looks like it could be power problem

Are any of these related and what do they mean exactly?


That is a direct copy of the receipt I got from the stealership. It only cost me 35 bucks though to get it scanned after I argued with them.

The link from techinfo doesn't really give much more.

I'd group the spark, crank and ign ones together and assume you'll find one thing causing the problem. You already did the plugs/wires/checked coils right?

The cruise...optional for now. Put off til later.

EGR...definately something to jump on. Did you try cleaning and putting back on with a fresh gasket? If not I'd be inclined to consider a junkyard...new at my local Advance they are $130ish.

The ignition problems involving crank codes are probably best handled by a vet...I haven't run into these issues before.

If I remember right it was either the crank or the cam senor that requires removal of the balancer which one?

EGR is the first priority (as willwren said lol)
I was told that these EGR valves on the 94+ dont react to well to cleaning.


Cruise is vaccum related


P0705 is scary.

P0341 as well as P1361 likely means an ignition fault somewhere


Have changed Wires, Plugs, O2, MAF, TPS, Air Filter and that is it

I cleaned the EGR on my 95, but when I originally pulled it I found the valve was already moving freely and the cleaning attempt changed nothing. Plugging in and unplugging the connector 5 times had a HUGE effect. Cured my problem in fact.

The crank sensor is the one behind the balancer.
