1997 Mazda Protege - Transmission Code

civicsi1279 · Post by **civicsi1279** » Mon Aug 03, 2009 5:05 am

i have a 97 mazda protege w/ 1.5 auto. the overdrive like will start blinking every once in a while and put the car in overdrive. i have scanned the computer and i will get a speed sensor code. could a speed sensor cause this or is the tranny on its way out?

A blinking light typically is the computers way of telling you there is a problem, such as the MIL. Are you saying the light starts to blink and the transmission goes into high gear?
Speed sensor will usually cause them to fall out of overdrive.

What code are you getting?

i am getting a 715 turbine speed sensor.. when the light starts the blink the car shifts into over drive and rpms go up

Check the resistance of the sensor. If its is ok then test the wiring to the ecm.

all that checks out to be normal. could a speed sensor cause this

Heat up the sensor and see. is the computerunder the center consule? check it for water damage like a drink

sounds that since it's ccasional, it's a bad connection.

If the sensor, wiring, to sensor and ecm are all good then it has to be an internal problem

I would recommend you scope the output of the sensor and compare it to a known good signal.

I bet its the sensor but he says it is ok

Any news?

i put a new sensor in and still the same thing

even the dealer said there are wiring issues with these beauties. the leads have a habit of backing out of multi-plug.

brianp87 · Post by **brianp87** » Tue Aug 11, 2009 6:15 am

So we have good sensor, good wiring, ecm or internal trans

i'm thinking its an internal issue with the trans

there are solonoids in the tranny that can cause these issues. too much line pressure can cause this.

brianp87 · Post by **brianp87** » Wed Aug 12, 2009 6:35 am

Does it give a way to check pressures
