HELP!! Maverick Front ABS Sensor

[lrsharpe]

Hi,

Can anybody help me to identify the Nissan part number for the ABS sensor on my 'P' reg maverick. The replacement that Ford have sent looks absoluely nothing like the one on the vehicle.

I have taken photos, and can email them if you can help.

Many thanks

Repairing Sensor

You might have tried this worked for me, not sure about the part??? someone will know :?

REPAIRING SENSORS

your old sensor can easily be repaired the sensor very rarely goes wrong its the wiring that connects it that breaks down and can be replaced by a competent DIY person or an auto electrician with very little kit needed you need a multimeter a soldering iron and solder some heat shrink (resin sealing is best) and some cable.

1. Too find the faulty sensor jack up and support the front of the vehicle on axel stands and remove the front wheels.

2. disconnect both front sensors from behind the rubber splash guard (follow the cable to the chassis) and unbolt the brackets that hold it to the suspension (do not remove the sensors from the hub as they will be rusted solid and you will damage them getting them out )

3. switch on your multi meter and set it to ohms connect the two leads to the two connectors inside the plug of the sensor lead (it doesn't mater which way round ) you should get a reading (1.1ohms to 1.3 ohms off the top of my head) get some body to hold the plug and multimeter leads while you wiggle the cable if the reading on the multimeter changes that is the faulty sensor you may have to bend the cable quite tight to find the broken wire its usually in the last bit of protective sleving (rubber hose ) before the sensor.

when you find the faulty one lay it on a piece of cardboard and mark the positions of the sleving and the brackets as you will need to remove these and put them back on later you can prixe the metal brackets off with a screw driver and after cutting the plug off the end of the sensor lead (leave a bit of cable to reconnect it) you can slide the sleving off with a bit of wd40

cut open the protective casing of the twin core cable and strip it back revealing the two cables work your way to the sensor you will probably see the broken wire just after the break cut the cable and find a length of new cable of the same size (this is important) there are plenty of car electrical shops that will help you solder the new cable onto the sensor and cover the join with heatshrink i use one that seals its self with a resin when you shrink it to make it water proof then cover both cables in heatshrink to form another protective layer and replace the rubber sleving anf support brackets and solder the plug back on the end and use heatshrink to seal it again reattach the support brackets and reconnect the plug replace the wheels and the job should be done make sure you check both sides as they may have both gone.

when you test it switch on the ignition and start the engine the light will come on for a few seconds then go out the pump under the bonnet will hiss once then stop road test the vehicle the light should stay off and the pump should not hiss under the bonnet.

hope this helps if not you will have to search the breakers for a second hand one which may not be in any better condition and they are as rare as rocking horse pooh trust me i have looked for one!

another thing that can effect it is the slotted ring that turns with the front hub the sensor has a magnet inside it and when this slotted ring turns it senses it and tells the abs Ecu the speed at which the wheel is turning the Ecu monitors all the wheel speeds if the abs senses that a wheel is about to skid it turns the brakes off it activates the abs mode on that wheel. The trouble is the slotted ring gets clogged with mud grease and metal fillings from the brakes and the sensor is fooled into thinking the wheel is skidding.

POWER SUPPLIE FUSES
Check fuses, 21-10amp, 25-10amp, 28-10amp, 49-20amp and fuse 50-10amp these are power supplies to NATS and the ECM.

Hi,

Thanks for the advice, but unfortunately the original sensor is broken and will have to be repaced

 

[Toolbox]

I may be completely wrong on this, but I think the early sensor is no longer available.

Try parts gateway for a second-hand one.

Thanks

Sorry I have been away But I do know all about these sensors and can confirm they are no longer availible for the front.

nissan who have them made in there infinate wisdom changed the sensors from ones that just fit the terrano and maverick to a sensor that is common accross there vehicle range

unfortunatley to enable the sensors to fit you have to buy
2 front sensors,
2 front bearing carriers the part the sensor fits in,
2 new style rear sensors because they have different values to the old style ones and the values need to match the new front sensors,
a new abs ecu because the sensors now work at different values and the last thing is the connectors on the ends of the new sensors are different and you cant buy just the connectors you have to buy a complete wiring loom so you can cut the connectors off and solder them onto your wiring loom.
Nissan technical sent me all the part numbers that i would need and i got the prices from my local nissan dealer and i thought that they had given me there phone number not a price of the parts.

The good news is you can pick up a good second hand sensor for about £35 they are handed but its only the metal fixing brackets that are different. when they go faulty its usually just the wire that is broken about an inch away from the sensor were it enters the protective rubber outer covering.

If you disconnect the abs sensor and undo the fixing brackets you can remove the wiring plug, fixing brackets and protective sleeving you can then cut the original cable off at the sensor leaving just enough to solder a new cable on then replace the sleeving, brackets and wiring plug.
but it is best not to try and remove the sensor as they can get stuck in the casting and get damaged when you tr and remove them.

Many Thanks

Hi Guys,

Mant thanks for your advice. I replaced a 8 inch piece of the sensor wiring and . . . . it now works perfectly :smile:

Joining this club was without doubt the best £10,00 I have ever spent :smile:

Just like to say thankyou to all those who posted problems AND solutions to the ABS problem.

I had the same on a Terrano 97 model, I bought about 3 weeks ago from an auction.

All of a sudden the ABS kicked in when slowing for no reason at all. Also no ABS warning light.

Did some checks and sure enough the cable on the nearside was showing continuity faults. Stripped it out and it was corroded and fraying. New cable manufactured and installed. Checked the bulb and the previous owner had taken the bulb out ! Great.... replaced the bulb, but didn't light up when the ignition was initially turned on. I wondered if the Guy before has snipped wires etc etc, but couldn't find anything. Checked fuses and and connections and all appeared to be OK.

Decided to take apart the dash again and check if the printed circuit showed any corrosion. All OK there. While I'm here I changed the bulb, just in case....

Voila ! a faulty bulb was the secondary problem.

The £10 membership has been worth every penny. Potentially saved hundreds of pounds, I guess that's why it was at the auction....

thanks again to all.

was ABS an option on the maverick? as my R reg doesn't have it.

 

[ronypony]

Must have been cos I don't have it either...I know abs is a safety device but having had problems with abs systems on other vehicles and experiencing the difficulties tracking down faults and getting them rectified I'm kinnda glad my Mav don't have it :smile:
