2006 Yaris (2NZ -FE 1.3) - P0010

Hi Guys

I've got a check engine light on after an alternator/ac belt replacement. First symptom was a check engine light, scanning it shows a P0010 code.

Closer inspection shows damage to the connector immediately above the alternator is damaged (see photo). What is involved in replacing this part? It looks like the whole thing has to be taken out and replaced.

Additionally, this is my only car. Is it safe to drive it in in the short term to work and back without any further damage as I source replacement parts?

I think you may need a new Oil control valve sensor. Common problem when changing the belt due to its location. It is in the frigging way and gets damaged so you have to make a conscious effort to avoid it.

Ok - I replaced this sensor. It doesn't require removal of the alternator, it is actually quite easy.

The steps are:
1. Remove the black cover (the one with the VVTI Logo) at the top of the engine*(4 bolts)
2. Remove the metal bracket that holds the alternator to the top of the engine
2a. Maybe remove the connection plug for the injector if you need extra room and move the harness out of the way
3. Undo the bolt that holds the sensor in place (10mm) then take out the sensor.

As I was removing the sensor, I actually snapped off the black piece. Then when I grabbed onto the body and pulled it, the body came out but the actual sensor itself got stuck INSIDE the engine. I googled it and apparently THIS is also a common fault so please take care when removing yours.

I was able to remove mine by gently pulling it with vicegrips / pliers but you may not be as fortunate. One guy I found that had this problem had to remove his bumper and thread a bolt in there to remove it.

Take care when removing this thing.
