My ETS and Service engine lights are both on. Volvo replaced the ETA and updated the software (recall) last month. ETS light came on about two weeks after replacement so I hadmy spark plugs (Bosch)changed and in the process the mechanic thought he broke a plug connector (#2 plug). I bought a new one from Volvo ($70), but the light is still on. Runs pretty good, but sluggish of the line. Any ideas? Do plug connectors gradually fail or do they either work or not? Online, I found replacement connectors made from Prenco for $20, will this be a good replacement?

Thanks

 

Hi,

I would visit an auto parts shop, such as AutoZone to have it free-diagnosed via OBD-II. Then I would buy a quart of oil/tranny fluid/light bulb/washer fluid as a courtesy (but this is jut me). Have them pull codes/trouble descriptionsand then post them here, so we can help you better.

This is a vendor some of us patronise:

I wish this gives you some hints.

What is the code that comes up now?

 

Sorry, I've been out of town so haven't had a chance to have codes checked. Engine service light isn't on anymore.

 

Good for you, that's the beauty of electronics; no one can figure out the problem including those who designed it[8D].

Code readings and explanation from printoutfrom autozone:
Code readings: P0220- the PCM has determined that a malfunction exists in the electrical circuit for throttle position sensor "B". Troubleshooting definition- TPS (throttle position sensor)/APP (accel. pedal position) performance condition. explanation The powertrain control module monitors the (TPS) throttle position sensor/(APP) accelerator pedal position sensor for errors. Probale causes 1. TPS or APP sensor shorted or open. 2. check connector and wiring to sensor.
Code reading P1672 (said for GM)- low engine oil light control circuit fault. (said for Acura)-A/T data line failure, possible poor electrical connection or failed module.
