#338 of 381 Speedometer by ewp

Oct 02, 2011 (6:50 am)

I have a 2002 Axiom and had transmission problems that resulted in Isuzu changing my transmission at their expense. When I picked up the vehicle the speedometer did not work. That problem also created a check engine light. The heading indicator also did not work even tho the satellite indicator showed I had satellite reception. I quickly turned around and told the maintenance supervisor. He took the car back and after a couple more hours on the rack came back and said I needed a new "Speed Sensor" and for $485 he could fix that.
 
My question is, where exactly is that speed sensor, a picture would be nice, and what does that sensor look like? Thank you so much for and help. EWP Pappy

Wow. That's a thorny situation. For one thing, if all of these features worked beforehand, your mechanic has some explaining to do. To make matters worse, there are multiple speed sensors on the vehicle, depending on whether it has TOD/4WD or not, although it is clear from the Service Manual for the 2002 Axiom that the speedometer is tied to one of them and its failure will post a DTC trouble code.
 
To be clearer, there are speed sensors at the front wheels, a speed sensor on the rear end for the ABS system, and one on the tranny body itself, and possibly a few more if you have 4WD. All are shown and described in the Service Manual, which you can buy and download online.
 
Or, you can send me a private message to "inboxatbancca.org" (Only replace the "at" with the symbol), and I can send you the 3 pertinent pages, which show the sensors in question.
 
If I were you, I would take the vehicle to another mechanic and get another price right off, and also an opinon as to whether the dealer is responsible for possibly damaging your speed sensor when they repaired or replaced your tranny. What may be happening here, if it is the speed sensor on the tranny body itself, and I think this is the case, is that some Neanderthal shade-tree mechanic damaged your speed sensor during the tranny repair or replacement and now wants you to pony up hundreds to replace a sensor that probably costs $100 or less. I just hope they did not do additional damage beyond the speed sensor to other sensitive modules in your Axiom.
 
However, do your own due diligence on this. Since it's a 2002, there is the possibility that this is coincidental failure; however the sky high repair price leads me to believe otherwise. This is where finding another professional who can give you another estimate is crucial - otherwise you might want to repair it yourself. Looks like an easy swap out - not much harder than replacing an oxygen sensor really.
 
Last but not least, if this turns out to be the dealer, don't forget you can file a BBB complaint, a complaint with the attorney general of your state, or you can march them into small claims court for next to nothing. Just be sure to document your side first, if you opt to do this.

i also own a 2002 axiom with transmission problem that has been rebuilt approximately 40,000 miles ago (115,000 miles odo). currently the transmission is jerking when it is shifting to second gear particularly from cold start. i may have to have it rebuilt again. the problem you encountered with no speedometer reading, wrong display of heading, cruise control inop, is caused by a worn out driven speed gear-part number 8-97144-659-1. it's available at dealer part only, $43.22 plus tax. installation by dealer from our area is $135.00. i have a reliable, knowlegeable mechanic here in orlando who installed it for only $35.00. my mechanic also have replaced/installed the following - new a/c compressor & dryer-$700.00; water pump, timing built & timing tensioner-$400.00. the interior of my car is still immaculate so i'm keeping it for a while as long as i have my reliable mechanic servicing it. the shocks are also in need of replacement, so i'm replacing the original electronic absorbers with the standard monroe absorbers. answer to your question is http://www.myisuzuparts.com/2003/893/2/2-25/showparts.html

#342 of 381 Intelligent Suspension Control- ISC shocks by massmusclecar

Nov 09, 2011 (10:19 pm)

The 2003/04 base model axioms did not have the ISC system, and some other standard features- they just had basic shocks and they seem to be readlily available aftermarket. they might be the same part number as rodeo. So far my ISC shocks are fine, a bit of weepage in one of them but they still feel firm. The ISC unit on the top of the shock basically limited the amount of movement in the shock by opening and closing a valve that controlled the number of steps in the shock valve damping. If I recall from 7 steps to 4 for the firmer sport ride.
For a better ride, be sure your tire pressure is no more than 3 pounds above the standard 26PSI. Regards.

#343 of 381 Heater blower doesn't work when COLD! by arkyax

Nov 11, 2011 (8:40 pm)

I have an '02 2wd Axiom with a strange problem that I haven't seen on the board. I live in Arkansas and when it gets really cold outside (low 20s or lower) my heater blower motor doesn't run. It happened several times last year.
 
I live a couple of miles to work and normally I can start the truck and let it warm up a little and before I get to work, the heater is blowing hot air. On these really cold days I have driven for up to 30-45 minutes before the blower will start working. When it does, the air is hot.
 
The engine is up to temp but it seems dependent on cabin temp and not engine compartment or engine temp.
 
I've mentioned it to people. One suggested that I had an air pocket in my coolant and I pulled the radiator cap and let it run for a while to see if the bubble would come out and the coolant level change. No change.
 
Any Ideas? Thanks

Radiator bubble...? LOL Try banging your fist around under the passenger side of the dash. My blower stopped working and I needed a new blower motor--this made it click on until I had it replaced.

Late year and again this year I have had an intermittent prob with my blower motor. It seems when it is cold and it is on a lower speed I get this bearing whinging noise but it seems to go away when I put the speed up or it warms up a bit so i assume after 10 years it is getting tired. I also wondered if something/debris might be in the blower motor cage. noise tends to go away so have not had the time to check under the dash and see how hard it is to replace the motor. anyway have an idea? cant be any worse than what we did to replace the motor in a late model camry. whole dash had to be taken apart to get at the heater box and motor. full day job and it was not pretty.

I replaced mine on my 02 Axiom for the exact same reason you describe. It was making the same noise... easy to do, easy to access, too. Just remove the connector and take out 3 or 4 screws and it comes right out.
 
I did find some leaves and debris in the squirrel cage when I replaced the heater blower motor with a new one, so in retrospect, if I had it to do over, I would remove (drop) the motor, clean out the debris, and lubricate it with WD40 or similar product, and see if it works WITHOUT replacing it. If it doesn't fix it, you can always buy a new motor. I got mine on Ebay from a wholesaler, as I recall for less than $50.

Hey Arkyax: Looking at the Workshop (Service) Manual for the '02 Axiom, I can see in the wiring diagram that electrically upstream of the blower motor, there is first a heater control relay, followed by two 15A fuses that feed power to the blower motor. There is no T'stat switch, per se, but the other side of the motor control is tied to the Auto A/C control unit (PCU) that does have inputs from three temp sensors - a duct sensor, an ambient air sensor, and an in-car sensor, which show up on the wiring diagram as some type of thermistor or other resistive temperature sensor or element. Two of them are stand-alone and appear to be easily replaced if defective - the duct sensor and the ambient sensor. The in-car sensor is shown as being part and parcel of (an integral part of) the intake actuator. There are three actuators, too - think of them like dampers - an intake actuator, a mix actuator and a mode actuator. This later one routes air to the floor vent or dash vent and so on.
 
So, I hope the problem that you are having is either a problem with the motor bearing lubricant, which can be easily fixed for $50 by replacing the blower motor, and is not related to the temp sensors, or the Auto A/C PCU. One test you could try, since it would not be hard to do, is to wait for a cold evening, remove the blower motor, take it inside where it's warm, then bring it out in the morning when it's cold and reinstall it and test it. This would isolate the problem to the blower motor and its bearings, which by now are probably getting old. If it is the blower motor it is REALLY EASY TO REPLACE, as described in my previous posting. Check eBay to see if the fellow I bought mine from is still selling new OEM Isuzu blower motors for $50 or so, if you opt to replace it, as I think the motor is about $100 from a dealer.
 
Hope that helps.
