Speed sensor issue - Hijet randomly slowing down

Post by HarryWhite on Mon Apr 24, 2017 7:01 pm

Hi jeters

I'm new to the forum and was wondering if anyone had any advice.

I recently bought a 2002 Hijet van and I intend to turn it into a camper. The engine warning light has come on and it's apparently due to the speed sensor. He previous owner mentioned there was an issue with this and that it sometimes drops speed when up around 60 mph. This has happened to me while on the motor way and it was a bit more dramatic than the previous owner made out. The speed dropped to 40 mph before kicking back in! I've taken it into a Daihatsu garage who confirmed the warning light is due to the speed sensor but they didn't sound to sure of why it was slowing down. They said to replace the speed sensor would mean replacing the whole dash unit for over £300. I'm a little dubious as they didn't sound as though they knew why it was slowing down and I'd rather not lay out 300 quid. I was wondering if anyone has experienced this issue and had any recommended fixes??

Thanks
Harry

Don't spend that £300! If you search on here you will find others have had the same issue. The issue is the sensor and its part of the instrument unit which is dead easy to replace. Secondhand ones are available from eBay and other sources for much less i.e. £20 to £50 on average. I presume being an 02 its a 1.3. The reduction of speed to 40mph is what happens as the Control unit is not getting the correct data.
Try this at only £10

Ullo 'Arry. Welcome to the the Machine. If by the sounds of your post, your speedo is registering your forward momentum then obviously the cable is ok.
Definitely the speed sensor. Easiest way is to fit another Instrument Cluster. I have some in stock so if you haven't found one yet, send me an Email to : thehijetmaniow@gmail.com and send your mobile number and I will give you a call. Woody.

Basically the speed sensor sends a message to the ECU. If that message is not being sent, the ECU thinks that the engine is in tickover mode and cuts the fuel. After a few minutes it resets and away you go again. If you keep your speed around 40 you can usually get by ok without it cutting out until you can put another Instrument Cluster in or change the Speedo Head.
