MAP Test / EVP OK?
Got a rough runn'in 91 Crown Vic that is giving me diagnostic codes 22 (MAP) and 34 (EGR). Both sensors are getting good voltage. The systems holds 5 in-Hg so I don't think I have a leak. I tested the EVP and here are my results: between 0 & 20 in-Hg, I read 3256 Ohms to 655 Ohms respectively. Haynes says that value should be between 5500 and 100. Are my readings bad or typical? Also, I do not have a tach to test the MAP. Does anyone know of an alternate method of testing it (maybe a volts conversion?).
Anyone tested these sensors before?
