Hi

Honda Accord 1997 SE non vtec 220ks automatics tran

everything is good, beside, i have one misfire cylinder, that im going to fix soon. til today i got the D4 light blinking, turn off the engine, the blinking stopped. 5 hours later, it started again and hasn't stop blinking, checked the codes and got that one. the car runs as good as always but im afraid if i drive it more, might go bad.

P1758 that is supposed to be the Lockup Solenoid Valve "B" Fault


Now i can not find any info on how to find it on my car, i think it is on the outside.

I've read all the post i could, but no answer to how exactly check and repair it

thanks!!

 

There are the two cylindrical shaped valves connected together on the top of your transmission. They are highlighted in red in the image below.



Most of the trouble shooting for this DTCode is chasing wire connections between the TCU, ECU and the solenoid. If you are comfortable chasing wires and have a multimeter with fine probes I can send you the procedure. But before all that check to make sure that the connectors for the solenoid are clean, free of moisture and tight.

 

thanks soo much you just saved me a lot of time looking around...

Im going to cleand them and come back to let you guys if i fixed....

 

already took the out,

the connectors have a green dirty in the metal part. besides that nothing abnormal

, im going to clean them up, and put them back on, to see if they get better.


i wont mind, if you put up the procedure

thanks!

 

I had p1758 reading . I went to a transmission shop and they said I needed a rebuild because my solenoids was working OK. No one seemed to be able to stop the check light or the flashing 4th gear. The car ran fine until the clutch went out3 weeks later. Replaced the transmission and now, I still get P1758 reading.
I wonder what the Dealer and Transmission shop will tell me now! I am reasoning it must be the computer or a wire. Why do I pay these people to LEARN their trade and still charge me!

 

Does your speedometer work?

 

my speedometer works fine
I am not using the car now - not until I find someone who knows how to trace wires

 

I recommend taking it to the dealership. We have the better resources than most shops when it comes to electrical diagnostics.

 

Someone told me it was the computer and the reason I burnt out the clutches was because the solenoid was not getting directions. The first mechanic told me it was going to "go" no matter what I did unless I had it rebuilt, yet he said the solenoid was working fine.
I now know that would have done nothing since it is only not getting messages to the solenoid. So i figure its either a broken wire or a bad plug or comp. It would be lovely if someone could just identify that for me. I can not afford to pay a dealership for a new comp - not on such an old car. Junk yards sell them for around $50.

Honda = the worst automobile i have ever had in 45 years! Even my old Corvair was better.

I appreciate your answer, thanks

 

What make model year is your Accord?

 

so if its a lockup solenoid, then replace it, not that hard it might **** a little fluid though but no biggy

 

yea back from the dead i know!
was searching an issue and saw this post an really wanted to add...

You're a phuckin idiot!

 

I just notice my post was revived.


the issue get solve getting another lock up control solenoid. three nuts and its out.

Theses thingies I learned get bad really easy, and the only fix is getting a junkyard one for 50 bucks, online you might find it cheaper...

cleaning, changing ATF doesnt help...
