f1 issue... code2

[kiekeboe]

CODES:


0 - bank angle sensor, ECM, PGM-FI fuse
1 - MAP sensor
2 - MAP sensor vacuum hoses, or sensor itself
7 - ECT sensor poorly connected or open circuit
8 - TP sensor, TP senspr wiring
9 - IAT sensor connection, or open wire
10 - Baro sensor, or connection, or wiring
11 - Vehicle speed sensor, or connection or wiring
12 - #1 injector connection, or faulty injector
13 - #2 injectior connection or faulty injector
14 - #1 connection or open/shorted circuit
15 - #2 connection or open/shorted circuit
18 - Cam pulse sensor, connection or loose sensor
19 - Ignition pulse sensor, connection or loose sensor
20 - faulty E-PROM in ECM.


2 - MAP sensor vacuum hoses, or sensor itself...

how can be seen as a map sensor is broken.
You can measure this with something?
if so what do I need.
and how I measure this.
possibly a link to a solution.

tomorrow I check whether or not the tubes are clogged.

Have you checked the hoses going to the sensor and the 5 way tee? These are the usual suspects for a code 2.

 

[dduelin]

Agreed. A code for the MAP sensor can be triggered by a blockage in one of the vacuum hoses leading from the four throttle bodies to the 5 way tee fitting that connects them. Many of us have cleared the intermittent FI light and a rough running or poor idle issue up by cleaning or replacing the hoses and tee fitting.

Today disassembled everything, and o'ja ..
I've found the problem.

needed a thorough clean.

Now everything is cleaned, test day tomorrow.

Please tell us that you replaced all the lines as well as cleaned the five way tee out...
The lines get old and hard from heat, and will not seal well if reused.
You can pick up some 4 or 5mm rubber tubing used for windshield washer stuff at most auto stores.
After all, you don't want to open that all back up again....
Be a good time to do the TB sync while your in there.

[kiekeboe]

yes I have, after the incident with the fuel joint.
had some some surplus Vacuum hose lying in the garage.
I change everything, where I have doubts.

keikeboe, good on ya! :yes:

One thing I noticed is that the throttle bodies show quite a bit of dirt/varnish on them, especially at the inlet to the idle bypass ports (where air is ingested during engine idle). If not too late, you should gently (dry, no chemicals) clean up the spots pointed at with green arrows in my picture below. Similarly, the underside of the air box should be cleaned off at the matching locations. That oily residue dirt is easily ingested into the fine idle bypass ports, affecting throttle body synch, at idle.

 

[kiekeboe]

yep, she was quite dirty.

most have already made clean.


This weekend there will be a technician with a Carb Sync Tool.
and then goes a little more thoroughly cleaning .

 

[kiekeboe]

oja my baby is running again ,
as smooth as a swiss clock.
f1 code 2 is gone.

 

[Igofar]

Great job!

 

[kiekeboe]

Great job!

tx... It has saved me at least some $.
free and fun to work on it.
and we have again improved somewhat.
