On an old Echo owned by a family friend.

Kinja'd!!!

She was complaining about her check engine light not turning off, and asked if disabling the light was worth it.

I connected my trusty, cheap scantool, and FIVE errors popped up. She told me a mechanic told her the repairs weren't worth it on the parts that were causing those errors.

The codes were the following; P0550, P0441, P0442, P0443, P0456. I've been reading that the P04XXX errors are common on Toyotas, mainly because another friend with a '03 Corolla had a P0442 this summer, and that was caused by a rusty fuel filler neck lip.

After clearing, the only code that stuck was the P0550, the engine was warm at this time, so I took the car for a fairly lively test drive around her block, and the P0550 was still the only error there. I also noticed the rear suspension needed new bushings on one side, as it was squeaking quite a bit.

P0550 is the code for "Power steering sensor circuit malfunctioning"


I told her that I could check the code again in a few days to see if anything shows up differently.

The P0xx codes will probably show back up in a few days. The series of codes says, to me, that the purge solenoid has gone bad.

Although it may not cause any immediate troubles, a faulty purge solenoid can cause further damage to the EVAP system, causing a loss in fuel economy and slight power loss. I'd recommend getting it taken care of in the near future.

She told me it's been like that for 3 years now, and that's when she told me the mechanic said it wasn't worth it. Perhaps the damage already happened.

My wife's Echo has P0442, P0443. Even though you cleared those codes, they will probably come back in a few weeks. In my opinion, not worth hunting down the gremlin causing it...I don't see it as affecting performance, gas mileage on our car. Your friend could try a new gas cap, and if that doesn't do it, black tape over the CEL.

I already followed up last night, 3 weeks after I made this post. The P04XX codes did not show up, and the only one was the same P0550 as before.
