eec 636 TFT sensor out of expected value
On 94 E150 5.8 EFI I'm getting code 636 on top of 122 and 121. Do I need to replace TFT sensor? Is it the temp sensor on valve body? Is it possible that something else is causing code 636 instead of TFT sensor? it is very cold out these days here in Indiana.
