Hi all, new guy here. anyways, trying to get my 91 lx back up to snuff. trying to fix the check engine codes. i'm getting a 1, 15 and 41. i have plans to replace the o2 sensor to clear he 1 and possibly the 41 but have no clue what the 15(Ignition Output Signal) could be. any ideas, common causes?

also, i'm trying the fix a small oil leak i have. i was told by the guy that did my tranny that it was coming from the oil sending unit close to the filter(he thought it was the filter till farther inspection). any ideas on that one? i will probly going to take it in for that one but don't wanna get screwed(i have minimal car knowledge).

 

Are you on BikeGuide??

 

yes.

 

Kind of a streach, but try looking at the distributor cap and rotor. See what kind of condition its in.

 

pretty good shape other then these problems. 1 lil spot of rust. since i have had it i have replaced both cv's, clutch, radiator, plugs and wires. runs good, never any major problems.

 

two things that i was just reminded of(i drive like once every 2 weeks):
first, when the car is not warmed up the idle will jump and drop from 1000 to like 2000 till it gets warm. but usually only when in gear.

second, sometimes it wont wanna start. it will turn over but wont fire. i only dose this once and a while. and then it will work fine in like 15 mins.

 

The ignition output signal is that circuit used by the ECU to tell the ignitor to fire the coil. I don't have a wiring drawing right now, so can't tell you what wire color. Look for dirty/loose/corroded connection at the wiring harness plug for the distributor.

It could explain your occasional non-starting too.

Don't do anything for code 43 (yet). There's a fair chance that code will not come back after you get the new O2 sensor and cleaned up the trigger circuit for the ignitor.
