Im receiving a TPS error as well as MAP sensor error on my DOHC ZC. I received the MAP sensor error as soon as I tryed swapping out the ZC tps with a Z6 tps. Doesnt look like they are compatible as Im still receiving the error and the z6 gasket is way too large.

My question is where is the MAP sensor on a 89 CRX HF?

 

bumpppppple bubbles..

 

its right next to the charcoal casnister on the firewall . Look for the thing with like 4 or so vacume lines comming out of it .

 

better yet , this post was recently made and has info on where it is and what it looks like https://honda-tech.com/zerothread?id=1244399

 

just went through this myself. I have an 88 HF should be the same and yes they are completely different from dx and si. here you go


and here we go:

 

awesome, thanks bud. to be honest, i dont think i have a map sensor on my firewall or throttle body. Ill go give it a better look in a few hours.

 

i used a Blox type B bypass, and kept a standard b16 throttle body not the one with a mapsensor on it. cause it dont fit my block. I can post a pic of it if U want. let me know.

 

if you have an HF, that should be it, it will say denso on it. unless when U had your swap done they ripped it out.

 

ok 88crxhfb16,
that looks alot like what I have. I didnt start receving the error till i tryed replacing tps sensor, any suggestions?

 

yes please post a pic, thankyou

 

heres what my engine bay looks like. I assume my MAP sensor is under that black box?

 

what do mean, what sensor did you try to replace? the one on the firewall? that my pic points to?

also it wont be untill tonight till I can get u some more pics up.

check back

later

 

yeah, remove that black box and it will look exactly like my pics. also you definately have a different Manifold than I got.

 

i tryed replacing the TPS sensor with a Z6 one, no luck, then I got the MAP sensor error after taking the z6 sensor back off.

So I guess I'll go looking aaround in junkyards today.
